Make your own bottle rockets!
All you need is: a piece of plastic plumbing tube (very cheap in any DIY store), a short piece of hose-pipe, an empty lemonade bottle, some paper, glue and Sellotape.
To make the rocket: roll a piece of A4 paper around the plastic tube. Use glue to keep the paper rolled up but do not stick it to the plastic tube! Push the paper over the end of the plastic tube so that you can fold the end over and stick it down with plenty of Sellotape. Take it off the plastic tube and that’s your rocket done…it’s that simple! You can decorate it if you like.
To make the rocket launcher: attach the hose to the neck of the bottle, again use plenty of tape to make sure no air can escape around the sides of the hose. Stick the plastic tube on the other end of the hose and make sure it is well sealed too. Your rocket launcher is ready to go.
To launch the rocket: Find an outside space that has plenty of room for a safe launch. Make sure the rocket can’t hit anyone or end up in a road. Slide the paper rocket onto the plastic tube. If you STOMP on the bottle, the air inside will be squashed and will rush through the tube under high pressure. This will make the rocket fly up in the air. You may want to get someone else to hold the tube so that you can get a really big stomp!
