In the newest Slow Mo Guys video, they shot eggs. I’m completely ignorant on why either egg explodes towards the path of the bullet. After it’s shot, you can see an even “explosion” in both directions. Why? What causes the egg to move in the opposite direction of the bullet. Please eli5.

This is what happens when you fire a projectile into a liquid object. Eggs are a solid shell with liquid inside – the yolk and the white- which is 90% water. Water is a non-compressible substance, so when the bullet hits the liquid of the egg, it causes an explosion inside the egg. The liquid will attempt to expand anywhere it can, in this case, being the hole in the shell made by the bullet. This causes the blowback towards the bullet.
Interestingly, this is why a person can die by getting shot in the arm, leg or other non-vital organ by a high-velocity bullet, even if it’s a small size. The water in the blood instantly expands to absorb the shock of the bullet, rupturing blood vessels in the body and possibly the brain. It’s called hydrostatic shock.
