My daughter has just popped up over my shoulder and literally begged me for one of these Trampoline Sprinklers. They look so much fun and for £24.99 they will keep the kids cool whilst bouncing.
It probably doesn't sound like the best idea, water + trampoline but there's an accident to be had in everything really. If you have a net up and monitor little ones on a trampoline then you've already minimised the chance of an injury.
These trampoline sprinklers are super easy to use, just attach the tube to the top of the trampoline, add your garden hose and the water will spray out over the top of the trampoline. You're in control of it so you can switch it on or off as you please.
It looks like so much fun and we all know how sweaty the kids get when they're bouncing about, this will certainly cool them down.
Get this one from Amazon for just £24.99 delivered, well worth the money in my opinion!
