A mousetrap car is a small vehicle whose only source of motive power is a mousetrap. Variations include the use of multiple traps, or very big rat traps, for added power. Mousetrap cars are often used in physics or other physical science classes to help students build problem-solving skills, develop spatial awareness, learn to budget time, and ...
Mousetrap, mouse, bait (chocolate) Wood mouse is captured with cage snap case An early patented mousetrap is a live capture device patented in 1870 by W K Bachman of South Carolina. [ 11 ] These traps have the advantage of allowing the mouse to be released into the wild, or the disadvantage of having to personally kill the captured animal if ...
Image of a guillotine-style mousetrap seller in the mid-19th century. In February 1855, Emerson wrote in his journal, under the heading "Common Fame": If a man has good corn or wood, or boards, or pigs, to sell, or can make better chairs or knives, crucibles or church organs, than anybody else, you will find a broad hard-beaten road to his house, though it be in the woods.

Step is based on bodies and forces placed by the user: Bodies range from tiny particles to huge polygons, and each body has unique properties that influence the outcome of the simulation, such as mass and velocity, and their derivations such as kinetic energy.
Mouse Trap (originally Mouse Trap Game) is a board game first published by Ideal in 1963 for two to four players. It is one of the first mass-produced three-dimensional board games. [1] [2] Players at first cooperate to build a working mouse trap in the style of a Rube Goldberg machine.
A bus trap in Denmark A bus trap in northern Aarhus, Denmark. A bus trap (car trap in the UK) is a metal grate placed over a ditch or pit in the road with tines (sides) spaced far enough apart that small (shorter axle) vehicles fall between the tines but close enough that larger-diameter-wheeled vehicles, such as buses, may pass.
The trap-forming hologram also can specify the mode structure of each trap individually, thereby creating arrays of optical vortices, optical tweezers, and holographic line traps, for example. [55] When implemented with a spatial light modulator , such holographic optical traps also can move objects in three dimensions. [ 56 ]
