Sponge Water Bomb

  • Kitchen sponges in various colours
  • String (or twine)
  • Scissors
  • Ruler

As the weather warms, here's a fun, active way to keep your kids cool by creating their own sponge water bombs.


  1. Grab 3 multicoloured sponges. Use a ruler to create little marks at the end of each sponge in order to create 1″ strips.
  2. Cut your strips, then stack strips three high and three wide.
  3. Be sure to mix different colours to create colourful bombs.
  4. Wrap your string down the middle around your stack.
  5. Once string is even, tie a tight knot. Double knot a few times.
