How Do You Make A Water Rocket?
Maybe we can’t launch a real rocket in our lives, but we can entertain us by making a water rocket! • Prepare two 1250 ml PET bottles. • Cut one of the bottles into three parts. Please keep the bottles top and middle section. • Stick the bottles top into the other PET bottle’s bottom part. • Stick the first bottle’s middle section into the second bottle’s top part. (Please use the insulating tape.) • Cut four acrylic boards as the four empennages of the rocket. • Pour about 200 ml Water into the bottle. • Cap the rocket into the inflater ready to launch. • Put the rocket into the launch pad. • Pump the air into the bottle. • Make sure the atmospheric pressure in the bottle is about 70~75 percent. Launch!
