I did one of these once.
My dad and I had this idea that egg yolks+whites have the right viscosity to protect a normal egg in a 30 foot drop.
We cracked about 7-8 eggs and put it all in a plastic container. We then slid the intact egg into the center and sealed the lid.
We went outside on the driveway and tossed the container up as high as we could throw it. Things looked promising until disaster struck.
When the small, plastic jar hit the ground, it exploded into a gooey, yellow mess, spraying eggs all over 2 cars and covering the drive way. This left a horrid mess that smelled like stuff. We spent quite a while hosing it off.
Good times! :D
