| Today I finded out this fun toy, the Solar Airship(GBP 12.5; about $25). It looks like an eight metre bin liner, you just fill it with common-or-garden air, and it will amply demonstrate the power of solar energy. When filled with fresh air and exposed to the heat from the sun, the solar airship rises majestically into the sky in the most dramatic visual demonstration of solar energy. See the video chick to here. Or check out the amazon for GBP 10. |
