How to Make a Waterfall Model With Real Water

Kids always want to know how to make a waterfall model with real water. There are many different ways you can do this, but here is one of the easiest ways to give your kids an accurate representation of what they would see in nature. First, fill the container with water and then create three columns on either side for each step in your waterfall process.

Then, get some blue food coloring and add it into column 1-2 tablespoons depending on the size of your container (you don’t want too much or not enough). Next, get some white vinegar and pour it into column 3-a a few tablespoons, also depending on the size of your container. Once you have done this, mix by rubbing them together until they combine well. Read this blog post to know more.

How to Make a Waterfall Model With Real Water

Things You’ll Need:

  1. Cardboard
  2. Duct Tape
  3. Water
  4. A Bucket
  5. An Old Laundry Basket (optional)

Instructions: How to Make a Waterfall Model With Real Water 

Step One: Make a Box

To make a box, you will need to start with a large piece of cardboard. The size should be about seven inches wide by seven inches long and at least five inches tall. To get the correct measurements, just set your ruler over the cardboard and mark off the dimensions.

Then cut three pieces seven inches wide by five inches tall and tape them together at their base to make a triangle. Finally, tape up all of the seams with duct tape.

Step Two: Make Paddles

To make paddles for your waterfall model, you will need one piece of cardboard cut into the shape of the paddle. To get the correct measurements, just set your ruler over an old credit card or gift card and mark off the dimensions. Then cut out that piece of cardboard and use it to trace more paddles with a marker or pen. Finally, cut them out and tape them together at their base in a triangle shape.

Step Three: Make a Bucket

To make a bucket for your water model, you will need to start with a plastic laundry basket. First, measure the width and length of the bottom of the laundry bin. Then cut out one piece of cardboard that is about an inch shorter than both measurements combined.

Tape it at its base to make a triangle shape. To strengthen it, lay another piece of cut cardboard that is the same size on top and tape them together. Finally, duct tape around all of the seams to make sure water doesn’t spill out.

Step Four: Fill It Up!

Now you are ready to fill your waterfall model with real water! Fill up the laundry basket with water and place it inside the box. Then lower the bucket into the water and watch your waterfall come to life!

Step Five: Make the Scene

Now that your waterfall model is complete let it run for a few minutes. Then take some time to think of ways to change the scene with what you have lying around. For example, you might try decorating the box with construction paper or paints before filling it up.

Or maybe you want to build rocks out of cardboard for the waterfall to run off of, or maybe you even want to cut out fish and other sea creatures with extra cardboard.

Step Six: Decorate the Waterfall Model

When your waterfalls are complete, it’s time to play! You can challenge yourself by racing boats down the falls without spilling any water out of the basket. Or, if you don’t have any boats, you can play by pretending that the water is a river flowing through your backyard.

Decorate the Waterfall Model

Notes: You can use a laundry basket because it has large openings on each side, making it easier to pour in the water without spilling it everywhere. However, you will need to tape up those holes with duct tape, so the water doesn’t pour everywhere when the model is upright. You can also use a plastic pitcher, or watering can fill up your waterfall if you don’t have a laundry bin available.

Some Tips and Tricks:

1) You will need to hot glue the curtain part of the waterfall at the top, where it hangs down. This should keep it from moving so much and getting out of line. Of course, if you don’t want to use real water, you can always stick a hose up there and tie around it, so it keeps running.

2) I had to use rocks and dirt, but try finding a fake rock if you want it to look classier. Or paint the bricks on the inside of the bucket “waterproof.”

3) The trick is getting everything into line so that it looks like a waterfall. You might have to play around with where things are placed before putting them in place.

4) It’s a good idea to use two buckets for this project because if any part of the waterfall is crooked, it will ruin the whole thing.

5) You can add plants and other stuff like that inside the bucket after you’ve made it and then fill it up with water (or fake water).
