Filled with sidewalk chalk paint, chalk bombs are a fun twist on regular water balloons. Not only are they fun to throw, they also leave a colorful splash behind. Store the extras in the freezer to make frozen marbles.
1. Make a batch of sidewalk chalk paint in the color of your choice. Pour the mixture into the water-balloon pump.
2. Fill the water balloons with the water-balloon pump and tie.
3. If you don’t have a water-balloon pump, you can also use an empty shampoo or lotion pump bottle. Another alternative is to fill the balloons with a water shooter.
4. Use them like regular water balloons, but watch as the paint makes colorful designs on the sidewalk or driveway as they burst open. Don’t forget to save a few to make frozen marbles!
