All adults are really children at heart, and this slip 'n slide would bring out the child in all of us. The slide itself is really long, and there's a ramp at the end that launches you really high and really far.

This would be really, really awesome, unless you belly or back-flopped, which would be incredibly painful.

This slip 'n slide is in France and would be a huge tourist attraction if they keep it where it is. Keep it open in warm weather and charge people to use it.  Brilliant business idea. A better idea would be some smart person in America building something awesome like this so we don't have to travel so far.
