Example #1 of the mouth open!
Carter would run the entire length and fall into the little pool at the end. It was apparently the best way to do it. Except when this happens...
Starting to slip...
And we're down!! But he didn't even cry. Which is amazing since he freaks out at most accidents. He must have been enjoying himself because this happened more than once.
He also would run and jump into the pool, purposefully falling on the way in.
More open mouth faces
So I would say the slip and slide is still a success based on what we've seen here!!
