DIY water mat?

[Household6]

Somebody has to have come up with a less expensive option or alternative for a large water mat, right?

Something like Rosso Water Floating Fortress - 18ft Floating Lake Water Pad Foam Mat For Boating, Lake, Ocean with Non-absorbent Tear Stop Technology Amazon.com: Rosso Water Floating Fortress - 18ft Floating Lake Water Pad Foam Mat For Boating, Lake, Ocean with Non-absorbent Tear Stop Technology: Toys & Games

I’m thinking of two uses for such a thing. The first would be as intended - multiple people on the same float. The second is to put it under a standard slip n slide so the journey is less “bumpy” and smooth.

(My search for “water mat” turns up an error indicating “mat” is too short of a word.)

How so?
The amount of fun it would be? Or the fact that I want to DIY it?

The price was what I was calling UNTIL I read it again as in read all of the words in the ad.............I did not notice how big it was nor did I open up the other fun pics. Now I will say it would be fun!!!! I say go for it!!
