If you take ARM & HAMMER Baking Soda and mix it with vinegar it creates this really cool fizzing reaction. The fizzing is caused by carbon dioxide being released from the reaction.
If you put a balloon over this 2L bottle and do the same reaction this happens. You can see we actually get quite a bit of CO2 gas from this reaction. We can then use this CO2 gas to build ourselves a baking soda rocket! Here’s how we're going to do this. We’re going to tape some of these wooden popsicle sticks on the side of our 2L bottle. Then we’re going to put some ARM & HAMMER Baking Soda inside a tea bag we emptied. Next we're going to pour in some vinegar and let the tea bag hang on the side of the inside of the bottle squeezed in between this rubber cork. The very last step is shaking up this bottle so we can get the ARM & HAMMER Baking Soda to mix with the vinegar. We’re then going to place our rocket cork side down on the ground quickly for lift off! So what we saw there was the CO2 building in the bottle and creating pressure. Once that pressure reached a certain point it forced out the cork and created jet propulsion. Now while we got the rocket to go straight up, in one of our tests we accidentally knocked over the rocket and it took off on the ground super-fast… it was a pretty spectacular accident. So this got me wondering, how far laterally we could get one of these rockets? To achieve this we built what we’re calling the Soda Rocket Launch Pad. This build consists of 2 PVC pipes fastened to 8 foot 2x4’s built in a U shape. The bottle rests in between the pipes and when the pressure builds it pushes back against our base plate and takes off! We will also have an adjustable 4-foot hinged leg that lets us change the angle of attack. We did this so we could dial in the right set up to achieve the furthest horizontal distance. We built our bigger soda rocket launch pad by attaching two 10 foot PVC pipes to two 10 foot 2x4s. We then made them into a U shape by attaching them with 1-foot pieces of wood. Lastly, we added a larger base plate and a 5-foot tall hinged leg just like the smaller version. Now because a 5-gallon bottle is about 9.5x larger than the 2L, we had to scale all of the reactants the same way. This means 4.75L of vinegar and 400 grams of ARM & HAMMER Baking Soda. We've also added dowel rods as legs and used a potato as a plug. We got our 2L bottle to go 85 feet before we super-sized the experiment to create GIANT BAKING SODA ROCKETS and got those to go 109 feet… totally insane!
