So this is a basic prank. Just emptying a soda can and replacing the contents with something nasty (Pickle juice anyone?) Its fast and easy as a last minute prank. This is my first instructable, sorry if its bad :(
Step 1: Materials
Soda of your choice
Awl, screwdriver, etc... (Anything that can poke a hole in the bottom of it)
Hammer to nail in the sharp tool
Undesireable Liquid such as pickle juice (MUST BE EDIBLE NO POISON)
Step 2: Empty the Soda
So poke a hole in the bottom of the can and let all the soda spill out.
Step 3: Insert the Drink
Pour the drink in through the hole until you feel its about half way or three quarters full so it feels normal.
Step 4: Cover the Hole and Place the Soda
Now just cover the hole with duct tape and put the soda in a place soda is normally stored in your house and enjoy :)
