Making a bottle rocket with baking soda and vinegar is always a fun and explosive (but safe) activity! When the baking soda reacts with the vinegar, it forms carbon dioxide and water. The carbon dioxide builds up inside the bottle until it launches into the air!
Here’s step-by-step directions to launch your own rocket:
Empty water bottle
Markers (or paint, crayons, etc.)
First Make Your Rocket:
1- Take a sheet of paper and color one side. This will be your rocket decorations.
2- Cut out a circle, cut a slit halfway, wrap it to make a cone and tape it in place. This is the top of your rocket.
3- Tape three or four chopsticks to the upside down bottle, with a few inches extending past the top opening. This will be your rocket legs, so make sure they are even and the bottle can stand on its own.
4- Wrap the decorated paper around the bottle, over the chopsticks and tape into place.
5- Tape your pointy cone to the top. You should now have something that resembles a rocket!
6- Wrap tape around a cork until you can plug the bottle easily but not too tightly. If it is too tight, it won’t shoot out.
Prepare to Launch:
1- Take a square of paper towel and put about a tablespoon of baking soda in the center.
2- Wrap it up to create a little baking soda packet. This delays the release of the baking soda and gives you time to put in the cork and get out of the way.
3- Fill your bottle about 1/3 with vinegar
4- Find a nice flat surface outside where you don’t care about the splatter. It makes a big mess when it explodes, but it is all easily washed away with water.
5- Push the baking soda packet into the bottle and VERY QUICKLY put in the cork. Make sure it is secure enough but not pushed in too far or it won’t pop out.
6- Give it a few shakes, flip it over and then RUN!
