I've finished my Physics project and it right sucks. Not only is it just plain ugly, but it's not heavy enough on the bottom, so it topples when you drop it with the egg in the compartment. HOWEVER, even with this, the egg still didn't so much as crack when I dropped it over our balcony (at a height of about 15 feet) and onto the cold hard tiles below. BUT, the actual drop is 20-25 feet (according to the project sheet), so there's still a high likelihood of that factor causing the pyramind to topple mid-air and crush the egg upon impact with the dirt. If the egg breaks, I get an 80. If it doesn't, I get a 100. I think I'm probably going to get an 80, but, I tried. -_-
