Tips to Make This Rainbow Bath Bomb Recipe

  • For a longer fizz-time, make a bigger bath bomb in the largest mold you have and REALLY pack the mix. A solid bath bomb will take longer to fizzle out.
  • Please don’t use food coloring. Your tub will likely stain with the red or blue and no one wants that.
  • This is a super-colorful recipe and would be perfect for anyone, male or female.
