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!
Solar Balloon by Tedco Toys. Made in the USA. 15 metre (50 foot) Solar Balloon and string.
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.
Don't forget to hang on to the control string - you want to be able to fly it again.
Properties of air
The 'gas' state
Not suitable for use in strong winds.
Keep away from power cables, overhead wires and trees.
Keep away from fire.
Use under adult supervision and do not place over your head.
Keep balloon and string away from young children.
The balloon is made from thin plastic sheeting to allow it to float. In the event of leaks, or tears, repair the balloon with insulation tape.
WARNING: CHOKING HAZARD - Small Parts. Not for children under 3 years.
