Mythbusters ideas for birthday party?

My almost 9 years. son wants to be a part of the Mythbusters. I think it an excellent idea, but have not made up but how. We live near a park with a large field and here is what I have to date. For experiments clearly Coke and Mentos, elevator, perhaps balloons, Patch Pirate steeplechase (at home, in a dark cellar), balls Golf, frozen .. Do you go further. And somehow get some ballistics jelly and a copy of the backyard ballistics book. To launch a missile little things and is designed to introduce the gel cast. Other ideas that could safe / easy? Also ideas for favors and decorations.Hazard ribbon? We also have an Estes rocket kit arrived at Christmas .. We can start to kick. Thank you

Your ideas are much more important. You can also see if you can find safety goggles and helmets cheap (like those in the toy, not real. The can be expensive). You can give each child one to wear to the party, then take home as souvenirs. I have no ideas more than that. Those to be occurring are great.
