Gemstone Donut Pendant

Gemstone Donut Pendant
Wear your love of geology around your neck! This beautiful Gemstone Donut Pendant is available in six different gems.

Watch in amazement as this ENORMOUS 15 metre balloon rises majestically from the ground high into the sky; powered by the sun.

The sight is remarkable. The Solar Balloon gains buoyancy when the air inside is heated by the sun's radiation. Just like a hot air balloon, when heated, the air inside the solar balloon expands - its low density compared to the surrounding air allows the balloon to float.

A powerful demonstration of buoyancy, convection, thermodynamics and solar power. It also teaches Bernoullis Principle and Pascals Principle. This giant sized science demonstration is great for engaging during science class, at a science party or fair. It's so much fun!

What you get
Solar Balloon by Tedco Toys. Made in the USA. 15 metre (50 foot) Solar Balloon and string.
How does it work?
After tying one end of the plastic bag with the included string, take the other open end and run along with it to inflate. The Solar Balloon requires 90% inflation to rise successfully. Once inflated, tie the other end off with the spooled control string. Expose to direct sunlight on a clam, cool day. The dark, black plastic easily absorbs energy from the sun, which heats the balloon surface. Air inside the balloon is heated by the surface of the balloon, and the hot air rises to lift the balloon skyward. Cool! Don't forget to hang on to the control string - you want to be able to fly it again.
