A juice made from red cabbage has a completely different color in an alkaline and acidic environment.
If a balloon is filled with air and held over a flame, it will burst immediately. If you fill it with water, it will survive the flame unscathed.
This article describes how you can build a water rocket with simple material, which flies up to 50m high!
In another article, the construction of the launch pad is then described.
Make miniature match-powered rockets with just a few household items!
