Homemade Water Walls are a great fun summer activity, we usually make one at the start of summer and leave it in place for as long as it survives.
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 to push it through or if someone blows down the end!
More importantly water walls are just great fun. My children have spent hours pouring, scooping and recycling water through the pipes.
What you need to build a water wall?
Empty Milk Cartons
Cable ties – handy for attaching tubes and funnels.
How to build a 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 through. 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 used elastic bands to attach the milk bottles.
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 that can either tip into a container to collect or drop onto the person below!
