Super Balloons
Bright and bouncy, these thick colorful balloons inflate to a super 30" dia! Great for homemade weather balloons, giant whoopee cushions, fun in the pool, or just kicking around the yard. Need strong lungs to inflate, so these aren't for smokers; swallowable, so they're not for kiddies under 8 either. Assorted colors.

Popcorn Rock…
That’s right, a rock that grows crystals that look sort of like popcorn! Just immerse it in vinegar and wait 1 to 3 weeks (instructions included). It looks like a roughly 2" lump of coal before crystal growth, in case you were wondering. Truly amazing!

Peltier Heat Pump
High tech comes to Am Sci & Surp!! It is here in the form of a Peltier junction, a thermo-electric device that translates electric power into heat, and perversely, into cool. Apply current @ 3-12 VDC to the gizmo and it extracts thermal energy from one face, thereby cooling it. The heat is dumped onto the other face, thereby heating it. Please note: you must use a heat sink on the hot side or the junction will fry itself, since it can quickly create a 65° C temperature differential in a no load situation. Stack two, or build a cascade to increase the thermal differential created. Or run it backwards. Apply heat or cold to the relevant face and produce a current. Amazing for science projects and experiments. Practical for coffee warmers, beer coolers and mini-refrigerator or warming oven applications. Comes with instructions. Large is 1-9/16" sq. x 3/16" thick.

Water, Water Everywhere
The Noah's Flood Alarm alerts you instantly to a leaking hot-water heater or an overflowing tub. Place the small, flat plastic sensor where water shouldn't be. A 10-ft white wire leads to a 3-3/8" x 1-3/4" x 3/4" plastic housing with an LED alarm and (2) "AA" batteries (yours, not ours). When the sensor gets wet, the LED will flash and a buzzer (think alarm clock) will sound and save the day.

Back To Basics
It could have been called an Alabama Buzzer after Alabama Vest, the man who invented it. Or a Clegghorn, after Thaddeus Von Clegg, the clock master who fabricated the first one. But the hand-crafted 4-3/4" long steel instrument was a simple amusement, and the 1840s were a simple time. So it's simply a kazoo.
