Make a Rocket With Two Pop Bottles
You can make a toy rocket that will actually fly: Toy water rockets are fun and you can make them from a few household and hardware items. You do not need any special skills to make the toy water rocket, just two soda pop bottles and a few hardware parts. An adult should supervise children taking part in the project, since it involves using a portable drill. Your toy water rocket will fly at your command and be ready to fly again within a few minutes.
