In this tutorial, we learn how to recycle a plastic bottle to make a toy bottle rocket. First, take a large plastic bottle and a sharp knife, then cut it in half. After this, take the side with the cap on it and then paint on the inside of the bottle. You can paint whatever you want on the inside, feel free to use different colors and get as creative as you want! From here, take some bottle caps and poke holes in the center of them. Then, string these together by pushing a string in the middle of all of them. After this, you will attach one of the caps to the bottle and let the string hang down. Then you can use this to throw in the air and catch the bottom cap with the cup, enjoy!
