This was seriously the easiest and quickest thing to make. All you need is a hose, pool noodle,duct tape and a chopstick (or anything else that can make small holes)
First close off one part of the pool noodle with duct tape. Then slide the hose into the noodle not to far ...I would say we placed ours about 6 inches in and tape it...Do not go light on the tape lol Make sure there is no holes in the duct tape. Then using what ever tool you choose (I found a chopstick to be perfect) poke some holes down the noodle.
Note the less holes you put the higher the water will go so do not put too many.
and Done! Simple as that and ended up being a lot of fun that we can reuse over and over again.
Side note we got our pool noodle at our local dollar store
