Water Trampoline - Pool Toys & Pool Floats
So, by the year 2050, anything on land will have a pool version. Water trampolines will be in their 25th edition and considered an oldie but a goodie pool toy.
This seems really cool. Apparently, the floating dolphins have a weight in the bottom so they're always upright and "dancing"
Shark fins are out, sea creatures are in ... the pool. Cheezy, I know. As kid-like as the kit is, your swimming could actually improve from minnow to shark to sea creature. Go you!
