Sick day kid hacks

We have had a sick boy on our hands and one of the many ways that he has endured it is dreaming up pranks and admiring this girl's hacks.  The balloon one especially keeps on giving and now I have a balloon phone case which I cannot show you because it masks my camera.  He's perfected this one!

We have started to make a list so we can unsystematically try them all.
Main ingredients, ballons, glue, glow sticks and more glue.
