The Best DIY Water-Play Ideas for Kids

Kiddie pools and sprinklers are tried-and-true backyard staples for kids on warm-weather days. Kick your backyard water play up a notch with my favorite fantastic and super-easy water-play ideas that will delight your kids. Plus, they’ll keep kids of all ages occupied and cool on any sunny, hot day.

Water wall

There is something about pouring water that can keep preschoolers engaged for hours. Use that fascination of water play to your advantage, and make a homemade water wall that will entertain toddlers and preschoolers all afternoon. Jackie at Kids Activities has all the details. Bonus: You can put this together with items probably sitting in your recycling bin right now!  

Paint with water

It’s a classic for a reason. Hand the kids paintbrushes of any size, and even rollers if you have some on hand. Fill up a bucket or clean paint tray with water and let them go to town. Kids can paint a fence, outside table, even the house! The water will make the surface change color temporarily while it’s wet, and will quickly dry in the sunshine.   

Build a stick raft

Head out into the yard, go on a walk or make a trip to the park to gather small sticks. Using string or another implement of your choice, connect the sticks together to form a small raft (you can construct a sail out of paper or leaves if you want to take the project further). Will your raft float? Time to find out! Fill a tub or kiddie pool with water (or walk to a nearby stream or lake), toss in your boat and see what happens. If it doesn’t float, challenge your child to think about why, make any necessary changes and try again. 

Jump rope with water

Jumping rope is fun, but jumping rope while holding a full cup of water is better! Hand the jumper a full cup (plastic is best, just in case it is dropped) of water and let them jump rope 10 times (or whatever number works for your crowd). After everyone has taken a turn jumping, whoever managed to keep the most water in their cup is the winner. Play as many times as you like! 

Frozen T-shirt game

This water-play activity uses water in its most summer-friendly state — frozen! 

If you have a crowd of kids to entertain, this fun group water-play idea is just what you’re looking for. It does require a little planning but is fairly simple: each child (or team) gets a T-shirt that has been thoroughly frozen. The first person to get the shirt defrosted and on, is the winner. You can fold the shirt up neatly or wad it into a ball before freezing. Try each method and see which one is trickier. Either way, this game is sure to be a popular one. 

Sponge balls

Preschoolers love this water-play idea that requires parents to make colorful “sponge balls” from dollar-store sponges. Cut two rectangular sponges lengthwise into four pieces each, then stack the strips into two layers of four pieces each. Wrap string or a rubber band tightly around the midpoint of the stacked sponges. “Fluff” and pull the sponge strips until you have a ball shape.

To play, give preschoolers a bowl or bucket of water to dip the sponge balls into. Wet sponge balls are great for tag, target practice or just tossing back and forth between kids. Check out Natural Beach Living for a more detailed tutorial.

Soda bottle sprinkler

Who knew a soda bottle could be so much fun! With a simple video tutorial, Gluesticks shows you how to turn your two-liter plastic bottle into an awesome sprinkler. Once it’s ready to go, you can lay the sprinkler on the grass, or toss the hose with the attached sprinkler over the swing set or a tree branch to make a “shower.”

Liquid chalk paint

Get your creativity flowing with this water activity. For outdoor art that is a step above sidewalk chalk, try making your own liquid chalk paint. First, purchase jumbo-sized washable chalk from your local dollar store. Now you will need to break up the chalk into a powder by either putting the chalk into a sealed plastic bag and pulverizing it with a hammer (preschoolers will love doing this, with supervision, of course), or grate the chalk using the smallest holes of a cheese grater.

Add the powdered chalk to a food-storage container and mix in water. Mixing about one-half cup of water per jumbo size piece of chalk results in a nice consistency. You will have a few chunks, but the mixture should be mostly liquified. Repeat the process with various-colored chalk until you have several different colors of chalk paint, each in its own container. Give the kids paintbrushes and let them paint the fence, a concrete porch or sidewalk, then turn the hose on their creation to wash it away and begin again.

Squirt gun target practice

When the kids get tired of squirting each other, set up targets for them to aim for. Draw targets with washable sidewalk chalk onto a fence. Draw several circles, starting with a small bull’s-eye in the center, then add three or four more circles around the bull’s-eye, each one bigger than the last. Assign each circle a point value and let the kids compete to see who can hit the most points (math practice alert). This game can work for almost any age, from toddlers to tweens. Simply adjust the size of the circles, and distance they must stand from the targets to take their shot.

Another target idea: Line up plastic drinking cups side by side onto a deck railing or stack upside down into a pyramid shape and fire away.

Water-filled piñata

Let the kids release some pent-up energy while cooling off with a piñata filled with water! To create this backyard water activity, fill a balloon about halfway with water and tie off. Using some string, tie the water-filled balloon onto a tree branch. Let preschoolers hit the water balloon with tennis rackets, plastic bats or a cardboard wrapping paper tube. Head over to ZiggityZoom Family for all the details.

These water piñatas won’t last long, but getting wet is the point of this water-play activity, and you can always make more with a large bag of balloons. 

Ice excavation

Freeze plastic toys into blocks of ice for kids to excavate! To prepare this water-play activity, fill plastic cups or small food storage containers about two-thirds full with water, and then drop one or two small toys into each container. Freeze each filled container until the water is a solid block of ice, then remove the ice blocks and place them outside in a large plastic bowl or metal baking dish. Now, let preschoolers figure out how to get the toys out of the ice.

Offer options such as salt, cups of warm water or squirt guns filled with warm water. Older kids can chip away at the ice with metal forks or butter knives. For a fun twist, try tinting the water blue with food coloring and using ocean-themed toys, or pair green water with tiny dinosaur toys. 

Water racetrack or lazy river

Here are two ways to let kids play with the magic of a self-created stream. For a racetrack, purchase a short length of a gutter (the kind on roofs) from your local home improvement store. Set the gutter up against the seat of a lawn chair in the backyard so that the gutter slopes down to the ground. See this post from Frugal Fun for Boys and Girls for a simple example. 

Place a garden hose at the top of the gutter and turn on the water. Preschoolers can float leaves, dandelions and bathtub toys down the waterway. You can even set up two “tracks” side by side and hold a race.

Or, make a lazier river by shaping aluminum foil into a gutter shape and putting it directly on the grass in a place where the ground slopes gently. You can use the hose to create the waterway or let the kids pour water down the river with a cup or bucket.
