marshmallows or gum drops
Insert the toothpicks into the marshmallows. Keep adding marshmallows to make any shape you wish. For example: star, hexagon or complex structures like a tall building or a bridge.
This is a geometry builder that many schools use in later years.
Give your little ones a head start...they'll think it's fun! It tastes good too!
Now I needed to build one because my husband and my sister in law (who lived with me while I was in school) would be so disappointed if I didn't make one myself.
Since I have a degree in Chemistry and all, I built a more difficult one.
Here it is, a caffeine molecule. This molecule is my favorite to build, that is why I remembered it. Also represented as C8H10N4O2 and the chemical name is 3,7-Dihydro-1,3,7-trimethyl-1H-purine-2,6-dione. I think I'm going too far with this information.
Anyway, this molecule is eight atoms of Carbon, Ten atoms of Hydrogen, Four atoms of Nitrogen and Two atoms of Oxygen.
