Here’s a real simple process for adding a bit of glow to sensory play.


  • Vitamin B-50, 2 capsules
  • Plastic Bag (maybe)
  • Wooden Spoon (maybe)
  • Measuring Cup
  • Table Spoon
  • Warm Water
  • Sensory Bin
  • Black Light
  • Assorted Water Play Props


  • B-50 comes in capsules and tablets. If you have tablets, place two of them in the plastic bag, close the bag, and use the wooden spoon to crush them into a fine powder. If you’ve got capsules, just pinch them open and pour the powder into the water as directed in the next step.
  • Fill the measuring cup with warm water, pour in the crushed vitamin B, and stir with the table spoon to dissolve the powder.
  • Fill the sensory bin with warmish water, pour in the vitamin B and water mixture, and stir with the wooden spoon.
  • Turn on the black light, turn off the other lights, and play in the dark with your glowing mixture.


  • Go big–fill a bathtub or wading pool with a big batch of the glowing liquid and let the kids play in it.
  • Make glowing ice cubes and play with them as they melt.
  • Try a black light florescent bulb or flashlight.
  • Consider letting the glowing liquid join in some dramatic play.

We’d love to know how this idea works in your play environment if you give it a try. Share your experiences in the comments.
