You may be saying to yourself, “I thought they just said that the fuel is in the gaseous state not liquid?”. The fuel used in the rockets like the ones that help the space shuttles enter space use liquid hydrogen as the fuel and liquid oxygen as the oxidizer. (Can you think of a reason why this might be important? Write your answer in the comment box below!) The fuel, in a gaseous state, is pressurized because this forces it out the end of the rocket just like our Film Canister Rocket! However, there are a few more parts to an actual rocket. The oxidizer is something that allows the fuel to burn without using outside air. ![]() These rockets use a pressurized fuel and an oxidizer. Quite simply, rockets are how NASA can get all those amazing missions off the ground. ![]() You already know what happens when you combine this chemical reaction with a film canister, when it pops, it goes up! (Has this reminded anyone of another great science experiment that uses a weak acid and baking soda? That’s right, baking soda and vinegar produce the same reaction when mixed together. Sodium bicarbonate is, well, basically baking soda. Citric acid is a weak acid and is in the juice of most citrus fruits like lemons or limes. When you mix these effervescing tablets with water, a chemical reaction takes place between the citric acid and sodium bicarbonate contained in the tablet and the water. This chemical reaction creates many, many bubbles of carbon dioxide gas. In fact, the company that makes Alka-Seltzer is so proud of the fact that it can be used in science experiments they have a whole page on their website dedicated to it! Not to rain on the Alka-Seltzer science parade but, just between us, the generic brands also work perfectly well for this activity and it saves some moolah! What is happening inside that film canister?įirst of all, we all know that the most common effervescing tablet used in a film canister rocket is Alka-Seltzer. KeyBank Discovery Theater Special Features.Be aware I am not a good photographer if the subject is moving. So here I am adding some pictures and finally publishing this Instructable. I decide to finish this one because all I had to do was make a rocket and get pictures and I would be done. I realized that I needed only to publish one or 2 more and I will have published 200 Instructables. Recently I started publishing Instructables again. It took a while to forgive him, and by then I was living life and not even thinking about it. ![]() I never saw it fly and I never saw it again. ![]() It went up, according to my hubby, and came back down and landed in the top of a 60 foot tree. Why? Because when my Hubby and I went to blast off my rocket and get pictures, my hubby, while I was getting my camera out of the car, choose to shoot it off. Yeah, 7 years ago and I never finished it. This Instructable is about how to make a 2 liter bottle rocket that will fly straight, true and far. Over the years, my rocket launcher has improved and so has my rocket. You could launch a 2 liter bottle rocket from this piece of pipe and it was very precious to me. Many years ago, I went to a Cub Scout activity and came home with a piece of PVC pipe with an O-ring on one end and a tire stem on the other. ![]()
