There was a problem filtering reviews right now. Please try again later.
It didn't take long for my boys to start experimenting with the water-to-air ratio to try to get a higher-flying rocket. Every time they tried something new I would say "what's your hypothesis?" and they would tell me what they thought was going to happen and we would compare it to what actually happened afterwards. The fun from this thing is infectious and pretty soon neighbors were walking over to see what was going on and cheered when the kids launched it. I took slow-motion videos (I attached images from one of the videos) and we watched them to see what was happening in detail. My kids will launch this thing as many times as I will let them (eventually I have to corral them back inside to wash hands and eat dinner...).
"Assembly" took about 60 seconds and I was slightly worried about bike pump compatibility after reading a few reviews that mentioned having issues, but, it comes with both Presta and Schrader adapters so no matter what pump you have, you should be covered. They might have modified the kit after reading negative reviews about only including Presta. I might have to buy a new bike pump actually because for the time being my kids have completely hijacked mine.
Bottom line: this thing is great fun. My kids have gotten hours of enjoyment out of it and show no signs of slowing down. We have shown cousins, aunts, uncles, grandparents, and everybody loves it. For the price, you really can't go wrong.
It comes with the bottle, screw for the bottle, the fins, 2 adapters for the bike pump, the tubing, and the plug for the bottle. After a quick setup and a little water, we were good to go. You just put a little water in the bottle, plug the end, then pump the bicycle pump about 3-5 times. We used a pump that you can put both feet on while you are pumping. The launch requires 30-40psi depending on how much water you put in it. Once you get the right pressure, it launches and uses the water as its propulsion. Just like the box says, it does launch about 30 meters high (90+ feet).
The instructions also included a couple paragraphs explaining the science behind the kit (action v reaction). I thought this was pretty neat. It never hurts to learn something while having fun.
We had asphalt and concrete nearby so the bottle and fins did get scratched when they landed on either one of those. Otherwise, I think you can get hours and hours of fun from just the one bottle without it wearing out. We will probably be testing out some different bottles to see if there is much of a difference in the launch or flight. I'm also thinking the bottle needs some tape for weight at the top so the fins don't hit the ground first.
I was worried it would use a bunch of water and the fun wouldn't last long. However, we filled up a gallon jug and that was good for about a dozen launches or more.
Overall, I would highly recommend this product. Yes, you can probably make it yourself, but for a ready-made kit, this is well worth the cost. The kit is meant for kids 8+, but it is definitely a fun thing for younger than that if there is proper supervision. Unfortunately, my 3 year old could only pump a few times before the pressure was too high, but I don't see older kids having any trouble with it.
WOW. We headed out to the local park (with water supply) with the box, with several little boys, with some empty soda bottles and a bike pump. Turned out we did not need the extra bottles, but they did work just as well as what was in the kit. Set up took only a few minutes. It is rare that a boxed toy exceeds expectations. This one did! The online ad said 30 feet, but the box says 30 meters, and that was more like what we got. The kids could do the pumping, although it took some effort. The rocket flew into the sky at least a hundred feet. This toy rocked.
By 30 minutes in we had every kid in that park gathered around. We experimented with amounts of water(a third to a half full got the best results) and how hard we pumped Kids were lined up to run the bottle back to refill it, and to pump it. The rocket was safe for all but the littlest kids. AS it fell back down the lightweight plastic bottle gently bounced along the ground. The kids quickly figured out that if it had a dent, a pump with the air tube before adding water fixed it. One mom leaned over to me and whispered "Nobody better tell them that they are learning!"
I can not remember being as impressed with a toy before this. I was doubtful that it would be that great, I have been let down before. But, the rocket is still being asked for and played with more than a month later. It is a simple toy that engages imagination. We had close to 30 kids watching us play, and begging for their own. I wish it was not so hard to find out there, not a single toy store in town had one for sale.
The simplicity and safety of this particular kit makes it a winner for kids of all ages. I am online to order several more for children we know, and my husband is getting one for his birthday.
