This would be great fun for the kids, rated 4.3 stars and more than 500 reviews, now half price after using the 50% off voucher.
P.S. The same toy selling on eBay right now is more expensive at the moment.
Not sure how long the coupon would last.
CamelCamelCamel.
haha okay, cool.
I just brought one but I'm going to try this too!
Where did you bring it?
Sometimes this correction goes down well, sometimes it doesn't 🤔
All you need is a coke bottle, a rubber bung with a hole in the middle, pump with a needle (plastic or metal) that goes in the bung.
The friction from the needle will build enough pressure.
Use a few bricks to keep the upside down bottle stable.
Pro tip…tape a coin on top in the middle. Flies much straighter (like a gyro in a real rocket). Water in bottle…optimum is less than a third.
I may..or may not be a Science teacher in a public school and have to Macgyver all resources ; )
What we didn't know at the time is MacGyver was from the future and he had a smart phone with chatgpt.
Chatgpt - how do I build a nuke using a rubber band, a salt packet and a tooth pick.
Right…What you need to do is superheat that salt, then dip the toothpick in molten salt…. then use the rubber band to speed up the toothpick until it…..
I've done the same thing but with the valve from an old bike tire glued in the cap. Works a treat!
I seem to recall that there are projects like this using softdrink bottles. But at 10.99……..
Also, my youngest is 19, BUT I soooooo want to pull the trigger on this one.
Out of stock

"up to 50 Feet"
How much does it normally fly up to?
50 feet.
Do you want the average or median?
Are you implying it is not a perfectly symmetrical distribution? 😲
I'm not implying, you're inferring
this is jeff's blue origin
Does anyone remember jamin jets?
This will eventually fly right into the landfill

Is that you Bubbles?
Let's be real, 4.3 stars on Amazon is not a great rating for something like this.
For those of you with a 3d printer this print is quite fun and works exceptionally well: https://www.printables.com/model/86434-water-rocket-launcher
Mind you, I think I spend more than $11 on O-rings and the tire valve needed with the print.
