What are Sponge Bombs?

Sponge bombs are simply water balls made from strips of sponge and a rubber band or hair elastic. These water balls soak up water and are great for throwing around.

They can take the place of a traditional water balloon or ball in any outdoor game or activity.

Unlike water balloons, sponge bombs are reusable- and you don’t have to pick up tiny pieces of popped balloon when your kids are through playing.

How to use Sponge Bombs

After crafting your sponge bombs, simply fill up a bucket with water and dip the sponge bombs in the water to fill them with water.

If you’re working from home this summer and looking for screen-free ways to entertain the kids, sponge bombs are a great way to buy yourself some valuable work time.

Water bomb sponges are also great for entertaining kids at your next summer party or field day.

Everyone can have fun getting wet without hundreds of messy water balloon pieces for you to pick up from the yard later.

First, choose three sponges and cut each one lengthwise into three strips. I like to use three different colored sponges to make a fun, multi-colored water sponge ball. 

Stack the sponge strips in three rows of three, mixing up the colors. 

Wrap a hair elastic as tightly as possible around the middle of the group of strips.

Pull the strips apart from each other and arrange them into the sponge ball.
