1J11.20 - 2 x 4 Tower

Code Number:
Demo Title:
2 x 4 Tower
Center of Mass
Area of Study:
2 x 4 Blocks.

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.
