Before someone goes into take a shower in the bathroom, casually pretend to go into the other bathroom but quietly sneak into the other bathroom before the person goes in. Making sure all the lights are off lay down and casually pop up saying BOO! It was hilarious!
Before everyone gets up in the morning get your moms blow dryer put lots of baby powder in it when she wants to blow dry her hair and when she press the button on the blow dryer she'll be amazed or blazed!
Get a bottle of nail polish. Pour half of the nail polish out. Mix the remaining nail polish in the bottle with clear glue (Elmer's). Then, pour it on some plastic wrap or whatever you want. Then, once the mixture has dried, cut around the shape of the spilled nail polish. Place the nail polish on the floor in an obvious place. Put the empty bottle of nail polish next to it with no cap. Do this right before school so your mom can't bust you for spilling nail polish.
