Rocket soda1/31/2024 ![]() ![]() To understand the science behind this, you need to know how do the fizzy tablets work and act as fuel for your bottle rocket. Now, you must be curious to understand how small pieces of fizzy tablets can push your bottle enough to launch it like a rocket. You will observe that when you put the half-filled fruit shoot bottle upside down inside the jar after shaking it hard, the lid opens within no time, and the bottle shoots up like a rocket high up in the sky. Your fizzy bottle rocket will get launched!.Stand back and wait for at least three minutes.Make sure the bottle lid touches the bottom of the jar.Put the fruit shoot bottle inside the mug or jar in an upside-down position.Quickly put the lid firmly on the bottle and shake it.Now drop the broken pieces of fizzy tablets into the bottle.Take two fizzy tablets and break them in half.Fill half of the fruit shoot bottle with warm water.Take the fruit shoot bottle and unscrew its lid.*Product Links are affiliate links – Your support is highly appreciated Steps to follow 1 Mug or jar large enough to fit the bottle in an upside-down position.Few fizzy tablets ( Alka Seltzer/Berocca tablets).Steps to Make Fizzy Bottle Rocket Raw materials You can launch your rocket and that too without any powerful jet engine! Does this sound unbelievable? Let’s learn about the fizzy bottle rocket experiment to launch your bottle rocket. WARNING: A 2-liter bottle like these falling down on a car could put a small dent in it so make sure you're clear of parking areas.Do you know how rockets fly? Are you aware that they can not escape the gravity of Earth unless they are covering at least 7 miles per second? Kids often think about launching a rocket, or fly high in the sky like a bird! Although it is not possible to fly in the sky, unless you are in a hot air balloon or in an aircraft. We made nose cones out of paper and taped them on (they didn't last once they got wet but they also won't hurt anybody if they fall on you). We generally used a single bottle for ours. I purposely angled all the fins on one bottle the same direction so it would spiral as it flew (like how a bullet goes through a rifled barrel). I'm sure there's instructables showing this technique. I know, it's not very accurate but it's super-simple. The bottle releases once the pressure gets high enough. You end up with about the right amount of water and compressed air in the bottle. Push the bottle down pretty hard on to that and turn on the hose. We did these with my Cub Scout pack with a few differences We figured out that a garden hose in some areas has about 90 PSI pressure so we just slide a bottle down onto a PVC pipe that we had heated up (like with a candle) and pushed to make it swell a bit. If you want to learn how to build an easy launch pad that will last for years, HERE is the instructable I created to take you through the steps. The major complaint about the launch kit (on Amazon) is stability. This can be fixed by adding a few rubber bands (wrapped around) where the water or air is leaking to help create a better seal. With the high pressure, the hoses have the potential to leak. ![]() I'm sure I could launch more rockets per year, but the rubber stopper tends to dry-rot after so many years. I can usually go for about 3 years (launching 70-80 rockets each year) before the rubber stoppers wear out. If the rocket launched well the first time, I might bump the pressure up to around 100 psi. This is where I allow them to test out different amounts of water/different air pressures/different launch angles. If the rockets are in good shape (still have fins/nose cone can be straightened out) they can launch again. When I do this activity with my students after everyone has had a chance to launch the kids can retrieve their rockets. You will need a large area to launch over (football field or soccer pitch). Stand back, pull the string with a quick flick of the wrist, and watch it fly. If you use an air compressor, getting the pressure up to around 90 psi only takes about 10 seconds. ![]() You could use a bicycle tire pump, but it takes a lot of work and the time between launches increases. The launch kit has a valve for pumping up the bottle (like you would find on a bicycle). This is approximately 2 Solo Cups worth of water.Ĭonnect bottle to the launch kit (This can take some practice because it takes some leverage to get the rubber stopper into the mouth of the bottle).Īfter the bottle is secured to the launch kit, pressurize the bottle. (It's good to have a hose spigot close by and a 5-gallon bucket). I have used THIS KIT for many years and find the quality of the materials built to last.įirst, add about one liter of water to the BOTTOM BOTTLE. There are a number of different launch set-up kits that can be purchased online. ![]()
