1. The marshmallow game requires a team of two or more people to use 20 spaghetti noodles, a piece of tape, a piece of string, a pair of scissors, and a marshmallow. Try to build a tall tower in 20 minutes to support the marshmallow to the highest level without falling over.

2. Triangle stability. Using a triangle, as long as the toothpick is not broken and the joints connected do not fall apart, it will not deform.

3, make more strut type toothpicks to support. Marshmallow and toothpick hard to stick to try to make the force of the toothpick copy the vertical direction. Let the horizontal direction of the force is a little less successful.
