You know how to freak your sister out? Ok, here's steps
when your sister is gone/distracted, go get a lighter.
run back to the Ba
get some hairspray
light the lighter while spraying the hairspray and it creates a big flame
If you have the lighter poor rubbing alcohol on your hand and light it on fire. It will look like your hands are makin fire. But when the alcohol burns out the flame will burn you so dont be to far away from sink or keep the flame on to long
