Egg Drop Challenge-Competition day


On competition day our container failed earning us 0 points. Our container was a ball and had a diameter of 14cm and weighed 112.1g. We dropped our container from 5m.our container fell the fastest, it fell at 0.81 seconds.
I find that the restriction that was the most limiting was the fact that we couldn't use a parachute. I believe using a parachute would have made the challenge much easier. the most effective part of our containers design was that it could impact at any angle, there wasn't a certain way that it had to be dropped. Our lest effective part was how we cut the hole. We had to shove the egg into the ball therefore we weren't positive if it was fully in the center.
If we wanted to adapt our container to safely contain two eggs we would have to use a larger ball so you would have more cushion.Also if we had a larger ball we could cut two different holes for the eggs.
The image above is me taking our cracked egg out of our container. The video below is of our egg drop.

Physics grade 12. Feb.28

On test day our containers performance was bad at first. Our egg cracked the first time we tried it. We started off using a small cardboard box filled with cotton balls. We tried packing the box even more with cotton balls but it failed again. We decided that we needed to come up with a different idea so we found a foam dodge ball. The dodge ball was light and had a lot of cushion. We cut a hole in the ball and put the egg in the middle. We tested it twice and it worked both times. Both times we dropped it from the top of the stairs.
