AquaPod The Original Rocket Bottle Launcher Kit - Launches Soda Bottles 100 Ft Up in The Air - Fun Educational STEM Gift Idea for Kids & Teens - Great Science Toy & Outdoor Activity for Family

Big fun for youngster BUT safety 1st! Can launch those 2 litres very high if you pickup some add-on fins.

I bought both the rocket and optional fins. Don't buy one without the other. With the fins this rocket has a smooth, straight upward trajectory that appears to exceed 100 feet. With the fins the rocket begins to tumble early in its upward trajectory, which severely limits it's height. DO NOT buy this rocket for your kid to be used without adult supervision, and don't buy it if you are planning on using it in a backyard in town. You will never see it again after it's maiden flight. It reaches serious height. The pressure relief valve (a necessary safety feature) works exactly as it was intended, so with constant close adult supervision I would feel comfortable letting a preteen use it. Although it appears a bit pricy for a "toy", this rocket is well-designed and built with quality materials, so well worth the price.u

A couple of very small broken plastic pieces in the parts bag. Looks like 2 of eight clips from INSIDE the leg attachment. How would inside clips get broken?. I am gluing the legs so I am not returning it as it will be solid. One O ring was loose on the parts bag. 2 were in a small bag also in the parts bag. Directions could be a bit better as with most things- it points to the rocket base and says O-Ring. A wasted launch later I realized it needs TWO o rings. The one that was already on the launcher and one of the 3 that were supplied. Once assembled properly it really really launched WELL. Worked great. The nosecone that is supposed to hold the parachute ACCESSORY absolutely topples off at the slightest provacation. I think we can get enough landings without breaking the legs or design a better cone. So far so good. kids love it

Great endless fun. Younger get kids will need supervision. Best used in grass so it doesn’t tip over and launch at someone.

my 4 yr old son and my 70+ yr old parents both enjoyed watching it shoot the bottle into the air.

We used these for our middle school science class. We got a total of 95 launches out of each launcher with no issues. They still seem fine and we plan in using them next year. The ground stake got deformed after many launches so you might want to grab a few extras. We found that adding vasoline to the o-ring every 4-5 launches helped keep them intact. Overall very happy.

If I recall, every time there was a NASA Shuttle launch, there was a 50/50 chance the launch would be scrubbed. This launcher is similar.If you are willing to get a little creative, and very wet, you can show your kids a good time. Overall, we had a blast (literally), but there are some design flaws with this launcher.First is the valve. With no adjustments for tightness, I had some rockets that wouldn't launch at all, others that launched prematurely, and some launches that leaked half their water propellant before they launched.Second is the launch latch. It's hard to explain, but you pull it down with a string, but at a parallel to the ground, instead of a 45-degree or 90-degree angle down towards the launcher. This means that if you don't anchor the launcher into grass, you can pull the string, tilt the launcher, and launch the rocket straight at your face. With a slight design tweak, they could have made it so that a tug on the string would pull the launch latch *down* instead of *towards* ground control.Lastly, the launcher should come with some fins. They are available for $10-11 each elsewhere, but in my opinion, they are essential for any fun launches. At least one should be included here.Overall, this is a fun kit, but it could be sooo much better with two or three redesigns.

Best part was making kids figure out the best ratio of water to air in the bottle and how much to pump the air up. They figured it out quickly. Adults took a turn too.
