# What is the trick to knock off 3 blocks completely off of a pedestal when they are stacked up?

## You can knock three blocks off a pedestal by throwing an object at them. They should fall if they are hit at the right angle.

A pedestal desk is usually a large free-standing desk made of a simple rectangular working surface resting on two pedestals or small cabinets of stacked drawers of one or two sizes, with plinths around the bases. Often, there is also a central large drawer above the legs and knees of the user. Sometimes, especially in the 19th century and modern examples, a "modesty panel" is placed in front, between the pedestals, to hide the legs and knees of the user from anyone else sitting or standing in front. This variation is sometimes called a "panel desk". The smaller and older pedestal desks with such a panel are sometimes called kneehole desks, and were usually placed against a wall. From the mid-18th century onwards, the pedestal desk has often had a top that is inlaid with a large panel of leather (sometimes with a gold- or blind-stamped border) or baize for a writing surface, within a cross-banded border. If the desk has a wooden top surface, it may have a pull-out lined writing drawer, or the pull-out may be fitted with a folding horse to serve as a bookrest. Very few non-specialists call this form a pedestal desk. Most people usually refer to it as an executive desk, in contrast with the cubicle desk which is assigned to those who work under the executive. However, the term executive desk has been applied to so many desk forms as to be misleading, so the less-used but more precise "pedestal desk" has been retained here. The pedestal desk appeared, especially in England, in the 18th century but became popular in the 19th and the 20th, overtaking the variants of the secretary desk and the writing table in sheer numbers. The French stayed faithful to the writing table or bureau plat ("flat desk"), which might have a matching paper-case (cartonnier) that stood upon it. There were at least two precursors to the pedestal desk: The French Bureau Mazarin (a desk named for Cardinal Mazarin) of the late 17th century and the Chinese Jumu desk or scholar's desk, which Europeans knew almost entirely at second-hand, largely from illustrations on porcelain. Unlike the pedestal desk however these precursors had an incomplete stack of drawers and compartments holding up the two ends. The cases of drawers were raised about 15-30 cm (6-12 inches) from the floor on legs. When a pedestal desk is doubled in size to form a nearly square working surface, and drawers are put on both sides to accommodate two users at the same time, it becomes a partners desk. Thomas Chippendale gives designs for such tables, which were generally used in libraries, as writing tables in The Gentleman and Cabinet-Maker's Director (1753–4 and 1762). Pedestal desks made of steel sheet metal were introduced in 1946 and were popular in America until the 1970s. Called tanker desks, they were used in institutions such as schools and business and government offices. When the pedestal desk form is cut to about two thirds of its normal width, and one of the pedestals is replaced by legs, this is then called a right pedestal desk or a left pedestal desk, depending on the position of the pedestal. This kind of form is common for a student desk. The pedestal desk is also one of the two principal forms of the big campaign desk, used by the military in the past. It can then be considered a portable desk in a limited way since the writing surface could be easily separated from the pedestals, to facilitate transport. The three separate elements were often fitted with large handles on the sides.
Pedestal (from French piédestal, Italian piedistallo, foot of a stall) is a term generally applied to the support of a statue or a vase. Although in Syria, Asia Minor and Tunisia the Romans occasionally raised the columns of their temples or propylaea on square pedestals, in Rome itself they were employed only to give greater importance to isolated columns, such as those of Trajan and Antoninus, or as a podium to the columns employed decoratively in the Roman triumphal arches. The architects of the Italian revival, however, conceived the idea that no order was complete without a pedestal, and as the orders were by them employed to divide up and decorate a building in several stories, the cornice of the pedestal was carried through and formed the sills of their windows, or, in open arcades, round a court, the balustrade of the arcade. They also would seem to have considered that the height of the pedestal should correspond in its proportion with that of the column or pilaster it supported; thus in the church of Saint John Lateran, where the applied order is of considerable dimensions, the pedestal is 13 feet (4.0 m) high instead of the ordinary height of 3 to 5 feet (1.5 m). In the imperial China, a stone tortoise called bixi was traditionally used as the pedestal for important stele, especially those associated with emperors. According to the 1396 version of the regulations issued by the Ming Dynasty founder, the Hongwu Emperor, the highest nobility (those of the gong and hou ranks) and the officials of the top 3 ranks were eligible for bixi-based funerary tablets, while lower-level mandarins' steles were to stand on simple rectangular pedestals. An elevated pedestal or plinth which bears a statue and which is raised from the substructure supporting it (typically roofs or corniches) is sometimes called an acropodium. The term is from the Greek akros or "topmost" and pous (root pod-) or "foot". Often misheard "pedal stool". When a person overly idealizes someone (or something, an object or idea), it is often referred to as "putting them on a pedestal". The pejorative phrase "put on a pedestal" is often used to critique celebrity culture, an elected official or position of authority, about someone who is looked up to, held in high regard or revered. To an extent that an accusation or crime may have been overlooked or disregarded, when an investigation or criminal prosecution was later found necessary, because an abuse of position or social standing was committed.
Blockhead! is a game invented in 1952 by G.W. "Jerry" D'Arcey and developed by G.W. and Alice D'Arcey in San Jose, California. Originally consisting of 20 brightly colored wooden blocks of varying shapes, the object of the game is to add blocks to a tower without having it collapse on your turn. The first player sets one of the blocks on a flat surface; this is the only block allowed to touch the base. Each player then takes turns adding a single block until the tower collapses. The player that knocks over the tower on their turn loses. A player who loses three times is eliminated. The last player remaining wins. Blockhead! uses slang terms with a block theme: A player who has lost once is called a "square"; a player who has lost twice is a "character"; a player who loses three times and is eliminated is a "blockhead". The game was first published by G.W. "Jerry" D'Arcey in 1952. In 1954 Saalfield Publishing Company released the first 25-block version of the game. The design of the blocks has remained consistent through each edition, the only change being modifying the yellow “double hump” to be more heart shaped. Currently, the game is produced by Pressman Toy Corporation. Blockhead! was voted into Games Magazine's Hall of Fame and appears on the GAMES 100 list.

k. In December 1942 four convoys sailed into the island without loss, and during this same month some 200,000 tons of stores of all kinds were brought ashore.
In Euclidean geometry, a convex quadrilateral with at least one pair of parallel sides is referred to as a trapezoid in American English and as a trapezium in English outside North America. The parallel sides are called the bases of the trapezoid and the other two sides are called the legs or the lateral sides (if they are not parallel; otherwise there are two pairs of bases). A scalene trapezoid is a trapezoid with no sides of equal measure, in contrast to the special cases below. A trapezoid with vertices ABCD is denoted ABCD. There is some disagreement whether parallelograms, which have two pairs of parallel sides, should be counted as trapezoids. Some define a trapezoid as a quadrilateral having exactly one pair of parallel sides (the exclusive definition), thereby excluding parallelograms. Others define a trapezoid as a quadrilateral with at least one pair of parallel sides (the inclusive definition), making the parallelogram a special type of trapezoid. The latter definition is consistent with its uses in higher mathematics such as calculus. The former definition would make such concepts as the trapezoidal approximation to a definite integral ill-defined. This article uses the inclusive definition and considers parallelograms as special cases of a trapezoid. This is also advocated in the taxonomy of quadrilaterals. The term trapezium has been in use in English since 1570, from Late Latin trapezium, from Greek τραπέζιον (trapézion), literally "a little table", a diminutive of τράπεζα (trápeza), "a table", itself from τετράς (tetrás), "four" + πέζα (péza), "a foot, an edge". The first recorded use of the Greek word translated trapezoid (τραπέζοειδη, trapézoeide, "table-like") was by Marinus Proclus (412 to 485 AD) in his Commentary on the first book of Euclid's Elements. This article uses the term trapezoid in the sense that is current in the United States and Canada. In all other languages using a word derived from the Greek for this figure, the form closest to trapezium (e.g. French trapèze, Italian trapezio, Spanish trapecio, German Trapez, Russian трапеция) is used.][ In an isosceles trapezoid, the legs (AD and BC in the figure above) have the same length, and the base angles have the same measure. In a right trapezoid (also called right-angled trapezoid), two adjacent angles are right angles. A tangential trapezoid is a trapezoid that has an incircle. Under the inclusive definition, all parallelograms (including rhombuses, rectangles and squares) are trapezoids. Given a convex quadrilateral, the following properties are equivalent, and each implies that the quadrilateral is a trapezoid: Additionally, the following properties are equivalent, and each implies that opposite sides a and b are parallel: The midsegment (also called the median or midline) of a trapezoid is the segment that joins the midpoints of the legs. It is parallel to the bases. Its length m is equal to the average of the lengths of the bases a and b of the trapezoid, The midsegment of a trapezoid is one of the two bimedians (the other bimedian divides the trapezoid into equal areas). The height (or altitude) is the perpendicular distance between the bases. In the case that the two bases have different lengths (ab), the height of a trapezoid h can be determined by the length of its four sides using the formula where c and d are the lengths of the legs. This formula also gives a way of determining when a trapezoid of consecutive sides a, c, b, and d exists. There is such a trapezoid with bases a and b if and only if The area K of a trapezoid is given by where a and b are the lengths of the parallel sides, and h is the height (the perpendicular distance between these sides.) In 499 AD Aryabhata, a great mathematician-astronomer from the classical age of Indian mathematics and Indian astronomy, used this method in the Aryabhatiya (section 2.8). This yields as a special case the well-known formula for the area of a triangle, by considering a triangle as a degenerate trapezoid in which one of the parallel sides has shrunk to a point. Therefore the area of a trapezoid is equal to the length of this midsegment multiplied by the height From the formula for the height, it can be concluded that the area can be expressed in terms of the four sides as When one of the parallel sides has shrunk to a point (say a = 0), this formula reduces to Heron's formula for the area of a triangle. Another equivalent formula for the area, which more closely resembles Heron's formula, is where $s = \tfrac{1}{2}(a + b + c + d)$ is the semiperimeter of the trapezoid. (This formula is similar to Brahmagupta's formula, but it differs from it, in that a trapezoid might not be cyclic (inscribed in a circle). The formula is also a special case of Bretschneider's formula for a general quadrilateral). From Bretschneider's formula, it follows that The line that joins the midpoints of the parallel sides, bisects the area. The lengths of the diagonals are where a and b are the bases, c and d are the other two sides, and a < b. If the trapezoid is divided into four triangles by its diagonals AC and BD (as shown on the right), intersecting at O, then the area of is equal to that of , and the product of the areas of and is equal to that of and . The ratio of the areas of each pair of adjacent triangles is the same as that between the lengths of the parallel sides. Let the trapezoid have vertices A, B, C, and D in sequence and have parallel sides AB and DC. Let E be the intersection of the diagonals, and let F be on side DA and G be on side BC such that FEG is parallel to AB and CD. Then FG is the harmonic mean of AB and DC: The line that goes through both the intersection point of the extended nonparallel sides and the intersection point of the diagonals, bisects each base. The center of area (center of mass for a uniform lamina) lies along the line joining the midpoints of the parallel sides, at a perpendicular distance x from the longer side b given by If the angle bisectors to angles A and B intersect at P, and the angle bisectors to angles C and D intersect at Q, then The term trapezium is sometimes defined in the USA as a quadrilateral with no parallel sides, though this shape is more usually called an irregular quadrilateral. The term trapezoid was once defined as a quadrilateral without any parallel sides in Britain and elsewhere, but this does not reflect current usage. (The Oxford English Dictionary says "Often called by English writers in the 19th century".) According to the Oxford English Dictionary, the sense of a figure with no sides parallel is the meaning for which Proclus introduced the term "trapezoid". This is retained in the French trapézoïde, German Trapezoid, and in other languages. A trapezium in Proclus' sense is a quadrilateral having one pair of its opposite sides parallel. This was the specific sense in England in 17th and 18th centuries, and again the prevalent one in recent use. A trapezium as any quadrilateral more general than a parallelogram is the sense of the term in Euclid. The sense of a trapezium as an irregular quadrilateral having no sides parallel was sometimes used in England from c. 1800 to c. 1875, but is now obsolete. This sense is the one that is sometimes quoted in the US, but in practice quadrilateral is used rather than trapezium. In architecture the word is used to refer to symmetrical doors, windows, and buildings built wider at the base, tapering towards the top, in Egyptian style. If these have straight sides and sharp angular corners, their shapes are usually isosceles trapezoids.
