1. Head to art store and paint your masterpieces on canvas….Set up a lemonade stand and sell them along with some lemonade….or take a photo and sell them on craigslist…Who knows…You might make it big or a lot of money???
2. Get the blender out…throw in some ice and add different types of sodas(Mountain Dew with lime, Pepsi with orange, etc.) and fruits…Maybe you will discover a new favorite…or maybe you will just get sick???
3. Find or buy a tape recorder..or maybe you have that feature on your phone…record some interesting sounds and secretly mess with people making them wonder what it is they are hearing, scare them or simply have fun!
