multicolored 2x4 blocks, stacked

 

Code Number: 1J11.20

Demo Title: 2 x 4 Tower

Condition: Good

Principle: Center of Mass

Area of Study: Mechanics

Equipment: 

2 x 4 blocks

Procedure:

The 2 x 4 blocks are all numbered and have marks on them.  Starting with "12" on the bottom, place the blocks on top of each other and slide them out to the marked spot.  When you get done, they should form an arc with the top block being outside the area covered by the base of the bottom block.
