Product Description

Product Description

Experience exciting rocket-launching fun with this vinegar and baking powder fuelled rocket.

Make the rocket, take it outside, fuel it up and watch it blast off with amazing thrust and fly up to 30 feet.

Each kit contains a super lightweight rocket, rocket fins, launching pad, decorative stickers and full instructions along with fun facts

Manufacturer's Description

Launch your own Cosmic Rocket up to 50 feet into the air! When vinegar is mixed with baking soda inside the rocket body, a gas called carbon dioxide is formed. As more and more gas accumulates, the pressure builds until it is forced out the bottom and the rocket is launched!

Our first attempts were not too successful, because we used baking powder instead of bicarbonate of soda. This achieved several launches of 30 to 40 feet.
After we acquired the bicarbonate of soda, we achieved a better launch rate and finally achieved a height well in excess of 80 feet the landing however was onto tarmac which resulted in the total destruction of the rocket body. hence our search leading us to this site.

I only saw the rocket launch once! It accelerated faster than a firework. I waited for any noise on it's return to earth,but not asound,it's got to be in neighbouring hedgerow or long grass. Perhaps it will turn up when the leaves die back in winter - If I get it back I'll find a bigger launch space or tie a high vis. ribbon to it's tail. Be warned it flies alot higher than 50 feet!

This product is really good and very simple to do, however make sure you launch, and more importantly, land onto grass. Our first attempt was off concrete and was great until it landed back onto the concrete. Although there were no obvious breaks, the landing damaged the rocket and now the mixture leaks out of the bottom and it doesn't work anymore. As with the other review, we have purchased another as it is definately worth another go!

The ultimate boy-toy to teach science.
We were given this for Christmas and tried it out at home a few times where it was fun. However, it really came into its own at Cub Camp where we did a Science badge. We did an initial 'experiment' making volcanoes with vinegar and baking soda and then re-applied the process with the rocket. The kids learned a lot and had a ball.
Warning! You do need a huge open space for this - we used one end of a football pitch as it doesn't always fly straight up. Think fireworks! Keep the kids well away from the rocket, once the stuff is mixed, even when it looks like it won't launch - it has a phenomenal power. Highest we got was about 65 ft.

DO NOT BUY THIS PRODUCT IT DOES NOT WORK PROPERLY

The seals leaked on the first one and so we tried to tighten the seal and the bottom of the rocket sheared off!

The seals leaked on the second rocket (heard that before?) we did not dare to tighten the bottom.

We are going to get our money back from Amazon.

This product is shoddy and does not deserve the name of the Science Museum!

Brought as a stocking filler for a six year old for xmas and it was well worth the money. Although he was too young to safely carry out the experiment and handed over to his Dad he was very excited and wanted to get outside and do it straight away but we didnt have the baking soda required. Tried a make do version of cream of tar tar with bicarbonate soda but didnt work. So if you are buying this make sure you have the vinegar and baking soda ready in your cupboard. Very simple to assemble rocket but even with the baking soda first 2 attempts failed to lift off. Does state that take off is affected by cold weather and warm weather are the ideal conditions, but on third attempt rocket went up great to much cheers after about a 15 seconds wait. Also, most importantly, it landed on soft ground intact so were able to do again although it did land 10 ft away so beaware of your boundaries. Very pleased, good value and would not hesitate to replace if it was lost or damaged.
