Homemade Water Walls are a great summer activity. We usually make one at the start of summer and leave it in place for as long as it survives. You can be creative and use a trellis, a fence, or anything else you can wrap tubing around. Add buckets and funnels for a summer of watery fun.
Our DIY water wall ideas are easy to set up with just a few supplies and work well in a school environment or garden at home.
Why Build a DIY Water Wall?
Water walls are great for teaching kids about gravity and how water flows. Charlie ( age 2 ) has already worked out that water will only flow up a pipe if there's enough force to push it through or if someone blows down the end!
Most importantly, water walls are just great fun. My children spend hours pouring, scooping and recycling water through the pipes.
We used a blue metal frame from TTS for this one with clear plastic tubing and funnels.

How to build a DIY water wall
Once you have a frame to build your water wall on ( this could be a fence, crates as we used below, or even a trellis ), the rest is up to you. Just attach pipes, funnels, and containers so the water can flow. It's a good idea to have something at the bottom to catch the water so it can be recycled through the water wall.
This is a very simple water wall we made using cable ties and a trellis.
Below is another example of a water wall we made using the metal frame from TTS. I attached the milk bottles with elastic bands.
Colour Mixing DIY Water Wall
This colour mixing water wall is one we made many, many years ago. First the yellow and blue water mixes as it drops into the bottle underneath, then the half plastic bottle under can either tip into a container to collect or drop onto the person below!
