This is REALLY easy but an AWESOME prank to do, as Asian Boy Obsessed  (_BRO0518_) probably knows.

You can just take water in a cup and put mustard or a yellow colored sauce inside. Mix it all up and serve to your family/friends at home/school and take pictures of their disgusted faces.

Tips:
• If you're at school, tell your friends that they are giving out free apple juice in the lunch line next to where you get the (insert food/drink) but they didn't see it for some reason so you got juice for all of your friends.
• Get your own cup of "apple juice" for yourself and pretend to drink it so it doesn't look too suspicious.
