How to Make Sponge Bombs

Welcome! If you’re new here, you may want to like our facebook page, or subscribe to our newsletter for projects and play ideas to do with your kids! Thanks for stopping by!

For a FUN time, here’s how to make sponge bombs!  Begin by cutting up ordinary household sponges into thirds, and wrapping an “ouchless” hair elastic around them….

Tip — Here is a quick video tutorial to demo how QUICK & easy these are to make!


Grab a friend and a couple of buckets — each person kneels in front of a bucket filled to the top with water. The object of the game is to hurl the sponge bombs into each other’s buckets! You WILL get wet!!!

Whoever gets the most in the other person’s bucket WINS!!

Gather up all the sponge bombs and play again (and again)! Mark and Clara joined in the fun too, but the camera would have gotten too wet, so you’ll have to take my word for it!!

This is a great way to beat the heat without using up a lot of water, and sponge bombs can be used and re-used all Summer long.

Have fun!!

  1. Those are nice and colorful and that looks like a blast!

  2. I trimmed the zip tie then used fingernail clippers to get the last bit. Super smooth!

  3. That looks like fun!

  4. That looks like so much fun. Thanks for sharing!

  5. Oh that would be a blast! More incentive to get that done…….

    • Valerie says:

      Yes! And they are SO easy to make! You’re going to wonder why you waited so long!!!

  6. Love it!!! Gonna have to keep this in my back pocket.

    • Valerie says:

  8. Fantastic idea!

  9. Melanie says:

    Great idea. I finally bought some sponges. How many “strips” did you use for each ball? Did you just stack them and then tie them off? Thanks … I can’t wait to try it out!

    • Valerie says:

      Hi Melanie — Nine sponge strips seems to be a great number. Just bunch them up (I did three rows wide & three high), and tie them up! Have fun!!

  10. I’m linking to you tomorrow. It was quite a while to find this post, but I knew it was here.

  11. I love these and am so going to make some.

  12. I love this idea…kinda like water balloons without the later clean up mess! I found zip ties and sponges at Dollar Tree — economical fun!! This idea will be put to use this summer…thanks!!

  13. I tied the balls together with cotton string.
    No sharp edges!!

  14. These are so much fun, and they make a great gift!

  15. What did you use to cut the sponges? I’ve made a bunch of these and they really dull an electric knife fast.

  16. I made them using the small rubber hair bands so no wire or ties required, we brought them to the beach and pool and they held up against a 3 yr old boy and an almost 2 year old girl :0) made 4 in about 5 mins

  17. Where did you find all the colorful sponges? I can only find boring yellow. :}

    • Valerie says:

      Our local dollar store carries them. I have also seen them at Target — hope this helps! Have fun, Launi!! 🙂

  18. I found this post on pintrest. We made these bombs today and had a great time playing outside with friends. They last sooo much longer than water balloons! We’re excited to use them again. Thanks!
