Mad scientist decorations are a breeze!
- Get balloons. Mylar (the shiny silver kind) look high tech, but you can use normal latex balloons for electricity science experiments. Helium-filled balloons are great for changing the pitch of your voice (illustrating density). You could inflate surgical gloves as decorations, too.
- You can print MSDS sheets or molecular structures for sucrose (sugar) or sodium chloride (salt) or lab safety signs. Biohazard is always a nice touch, though radiation is also cool.
- You can decorate a chalk board or dry erase board with equations or instructions for your science projects.
- Fill jars with food-colored water. Add plastic eyeballs, animals, fake body parts, or whatever you find that looks 'science-y'.
- Dissect a few gummy worms or frogs, pinned to cardboard.
- I highly recommend having a black light (ultraviolet lamp). There are several food and drink ideas that will glow under a black light, plus it opens up the possibilities for glowing party games and makes everything look cool.
- Replace your normal light bulbs with colored bulbs.
