Bull frog callers. You need yogurt containers, string and scissors. Have the
kids poke a hole in the bottom of the yogurt container. They'll need to do
this by twisting the scissors rather than by smacking them because the
container will just crack. (They can still be used if they're cracked, it'll
just be harder to hold the string in place with a big knot.) Feed the string
through the hole and knot it a bunch of times so that the string won't pull
through the hole. Or use a paperclip. It doesn't matter which side of the
hole the knot is on. Have the kids wet the string and then pull on it. The
string should slide through their fingers and make a croaking sort of noise.
Say to the kids, "You've made an unusual machine you can use for catching
frogs. How could you change the pitch of the sound you make if you wanted to
call bigger or smaller frogs?"
Don't forget tuning forks, corruga tubes.
And as a general note on sound workshops: have Tylenol nearby.

Oh, there's some good ones with sound!
1) A resonating aluminum rod can be really loud, and is cheap/durable/easy.
Usually marketed as the "singing rod" ie here:
http://sciencekit.com/singing-rod/p/IG0023754/ (Flinn Scientific even makes
them in different lengths)
2) You can get a lot of volunteers to help you, and kids love the Boom
Whackers
http://www.stevespanglerscience.com/product/1179
3) Ricci tubers (pipes with wire screen that's heated with a blow torch) are
also cool. It's not online, but Flinn lists them in their catalogue as
"singing tubes"
4) Wanna break the sound barrier? Just use a bullwhip. Takes a bit of
practice, but makes you look macho.

Hello,
We are planning our new "show" for the upcoming school year. We were
considering a show on Sound. If you have a fantastic Sound show, I would
love to hear from you. Besides the Ruben's Tube, are there some other
Wow-y, super cool demos, or is this a difficult one to make exciting?
If we don't go with Sound, I'd love some suggestions. We have Combustion,
Liquid Nitrogen, Chemistry and Air. What are your favorite shows and demos?
Thanks in advance for any feedback!
