Safety Note: It may take a moment for the reaction to build up enough gas to launch the rocket.Turn the bottle over, place on its ’legs’ and STAND BACK! Watch as the rocket soars into the sky. Working quickly, place your paper towel packet inside the bottle and plug with cork. Place the rocket upside down and remove the cork. Take everything outside to clear open area.Īdults or older kids only: I highly recommend wearing safety goggles for the following steps. DON’T add it to the bottle yet!Īdd duct tape to one end to keep the baking soda from spilling out. Roll the paper towel tightly enough so that it will fit inside bottle opening. Add 2-3 tablespoons of ARM & HAMMER Baking Soda onto the paper towel. Set aside.Ĭut a paper towel into a square. Add 2-3 cups of vinegar to the bottle and cork it. Turn the bottle over so that the pencil legs are facing up. Make sure the legs are placed high enough to allow for 1-2” of space between the bottle opening and the flat surface below.ĭecorate the bottle with duct tape, paper, and/or cardboard to make a rocket as desired. The bottle opening should be facing down when the bottle is placed on its legs. Secure 3 pencils to the bottle using duct tape to make “legs” for your rocket. Cork (make sure it will fit mouth of soda bottle).Construction paper/Cardboard Use to decorate rocket.3 tablespoons ARM & HAMMER™ Baking Soda.Today’s project is the fourth science experiment in a fantastic summer resource, Arm & Hammer Summer Camp. I’ve enjoyed being the camp science counselor so much! Blast Off Baking Soda Rockets Downloadable directions here Materials I mean how can you not love the anticipation of a good rocket launch?
Of all the experiments we did for camp this one elicited the most gasps and excitement. Today’s Arm & Hammer Summer Camp science project will require adult supervision at launch time. I may see it again in December when the tree loses its leaves. The chemical reaction used to launch Blast-Off Bottle Rockets produces enough carbon dioxide to propel the bottle high into the sky! So high that one of the three rockets I made is currently sitting in our persimmon tree 30 feet above ground.
