Pranks gone wild for years?

Question

ok me and my cousin always try pranking each other ever since the first time we met. LOL! nothing major like injuring or going to the ER. But it still continues to this day. So.....he might be staying with my mom till he finds a place to live ( he is an adult now ) and i want to set some things up in case he gets to my moms b4 i get back in nov. i was thinking like idk shampoo that turns your hair blue for a few days.
