Homemade Fall Wall for Kids
We originally called this project a “fall wall” because it is reminiscent of a waterfall wall with interchangeable obstacles and tubes to create new falling paths. In looking at other projects and toys that might be similar, the words “discovery wall” came up repeatedly.

Make a Homemade Discovery Wall from PVC Pipes
Tubes + Kids = Hours of play!
During the summer our kids love to play with water walls. We have a collection of piping that they rig up and pour water through the pipes, making a lovely muddy mess in our “dirt pit”.

It is one of their favorite summer activities…. and now that it is winter they miss their “pouring” play. It is why we decided we needed to figure out an indoor solution for a discovery wall.

Supplies Needed to Make Indoor Discovery Wall
- variety of PVC pipe connectors, small straight pieces and joints – we found that the 2 1/4 inch wide pieces were the easiest to drill through, easiest to pour through and still economical
- funnel and other plastic pieces you want to integrate into the discovery wall
- a suction cup for each piece in the discovery wall
- large plastic bin to catch the falling items
- measuring cups, large spoons and scoops
- beans, un-popped popcorn or other small material that will fall through the discovery wall
- drill
- (Optional) glue to secure suction cups to pvc and plastic pieces
Our discovery wall set was about 10 pieces total of pvc pipe and funnel pieces. You could make a much larger set. Making at least 6 pieces will give a lot of flexility when it comes to play.
We made our entire wall with roughly $10 by shopping sales at the local hardware store and checking out the dollar store too!

Directions to Make an Indoor Discovery Wall for Kids
Step 1 – Attach Suction Cups to PVC Pipe Segments
We drilled holes into the pipe connectors, matching the drill bit to the suction cup “fitter”.
- You want the hole to be slightly smaller than the connectors on the suction cups.
- We used a kitchen knife to help stuff the cups into/onto the PVC pipe fittings.
Once the suction cups are firmly inside the PVC tubes, they are really easy to press onto the window.
Tip: If your suction cups don’t seem to fit securely, then add some glue between the suction cup and the pvc pipe hole and allow to dry.
Step 2 – Build Your Discovery Wall
- Build the first fall wall on a window or sliding glass door. Try to make it so the beans will move from one piece to the next in a falling motion.
- Be sure to put a bin at the bottom!
- Pour the first cup of beans through the discovery wall to see how you did aligning the tubes.
Our kids played with the tubes and corn for HOURS!

LOVE, LOVE, LOVE this idea. Now, if only I can get my hubby to fix the drill.
Yahoo! It was easy enough that I was able to do it without my hubs…and I am not a “tools” gal. Have fun with it!!
I remember seeing that bathtub post, too, but don’t remember where it was! I love the tube wall, especially the suction cups! This is just SO cool!!!!
This looks like so much fun!! We need one of these at our house!
This looks like an activity kids would love, but honestly do the beans and stuff get all over the place or are they pretty contained?
This looks like so much fun!
This is what I pinned for the bath on Pinterest a few weeks ago : http://pinterest.com/pin/160722280423489943/
I hope to make this for my grandsons soon.
LOVE it!!! 🙂 Thanks for sharing.
Going to try it with sticky velcro on the tubes and then make a flannel “wall” since we’ve got plastic over all our windows. Hopefully that will work. And Faigie, yes, the beans go EVERYWHERE, but they’re a reasonably easy clean-up with the broom.
Great goods from you, man. I’ve understand your stuff previous to and you are just too fantastic. I really like what you have acquired here, certainly like what you are saying and the way in which you say it. You make it enjoyable and you still care for to keep it smart. I can not wait to read far more from you. This is actually a tremendous web site.
I seldom comment, but after reading a few of the responses on Tube Play How we transformed PVC
pipes into a “fall” wall. – Kids Activities Blog. I actually
do have 2 questions for you if you don’t mind. Is it only me or does it look as if like a few of the remarks appear like they are left by brain dead folks? 😛 And, if you are writing at other online sites, I’d like to keep up
with anything new you have to post. Could you make a list of the complete urls of your social community
sites like your twitter feed, Facebook page or linkedin profile?
This is a great idea! I got all the tubes from Lowe’s, but I’m having a hard time finding suction cups for a decent price. Where did you get yours?
