We didn’t include this particular experiment in our shopping list, as the tube’s kind of expensive and can only be used for one particular experiment, BUT it’s an incredible blast to do in the summer.
Here’s the main idea – a incredibly loooooong and super-lightweight black plastic garbage bag is filled with air and allowed to heat itself in the sun. In a few short minutes, the entire 60-foot tube tube rises into the air. Before you try this experiment, try the Hot Air Balloon first!
