Gigantic 50-Foot Solar Balloon
Create your own natural hot air balloon and learn some science all at the same time with this cool new Gigantic 50-Foot Solar Balloon from TEDCO Toys. Just unfold this humongous 50-foot-long black tube outside on a calm and cool day, fill it with air, let bright direct sunlight warm the air inside, and then watch in amazement as it begins to float into the sky with one end tethered to the 400 feet of included string. The warm air on the inside is less dense than the cooler air on the outside, so it begins to rise, demonstrating buoyancy, convection, thermodynamics, and solar power. It's perfect for science class experiments and projects or just send it up for the fun of it. If it happens to cause local onlookers to pull out their phones to snap pictures and videos of this possible UFO sighting... even better. Check out the video below to see it in action.
