Picture of DIY water slide
Every year our school has a sports day during the last week of school.  This year I built a water slide down the school's front steps as one of the activities for the kids (and adults) to enjoy.

Step 1: Materials needed

Picture of Materials needed
The exact material list will largely depend on your site.  Modify this list to meet your needs.  The most important ones for building on a set of stairs are the four Ps...
  • Plywood - You need some rigidity and a little flexibility.  Not too thick, not too thin.  Goldilocks would pick this thickness.  Somewhere around a half inch should be about right.
  • Padding - I was very lucky to have interlocking closed-cell foam pads that are about an inch thick.  You could use carpeting, carpet padding, camp mattress pads, the interlocking alphabet children's mats... With some time you can find something and with a budget you can buy something.  You also may need some padding with some higher friction to get people to stop; like an old mattress.
  • Pool noodles - small, giant, LED lit, glow in the dark...
  • Plastic sheeting
  • Tape
  • Garbage bags
  • Stairs
  • Hose and water

Aside from that being entirely awesome... you're in Mongolia? How long have you been there? How is that going for you?

We have been working here for two school years. Headed back to Alaska in three days and then in just over a month we're headed to Chennai, India for at least two years. Lucky for me that India is included in all contests!
Sounds amazing, how do you get to travel like that? Those teaching programs?

The travel is a huge benefit. I'm actually not even a certified teacher (yet). I don't work at a school that just teaches English. It is a full Pre-K-12th grade program with everything from Art to PE. Perhaps an Instructable on how to get an overseas teaching position would be good to write!
That would be an awesome ible!
I've been meaning to get in on that kind of work, but I've always had a hard time figuring out which programs are good or bad, and so on.

The only thing I could think about when I saw this was big stair sets and hills on my campus
