Idea and purpose:
The idea behind this prank is to freak someone out with what they find in there eggs. Its a pretty simple prank but i have personaly used it many times to make people ponder what went wrong when they were cooking,baking, ect.This prank should not hurt anyone if injested as it only "inflates" the egg. But to be safe, when you are makeing it use gloves(might not be necessary but better to be safe than sorry). Disclaimer*I am not responsible for any injury or illness that may occur as a result of this prank.*
A container(preferable with a lid)
As many eggs that will fit or you want to use
Step 1: Step 1:Putting It Together
First you need to get the container filled with as much eggs as will fit or as much as you want. Then you just submerge the eggs completley, (important that they are completley submerged) with vinegar. Close the contanier, if you have a lid, then set it aside to "grow". Usually takes about a day or two so do it in advance of the time you want to pull the prank.
Step 2: Step Two: Pranking Time
After the egg is completley "grown" then you can put it back in the container, Throw it, what ever you want to do with it. Have fun with the prank.
