DIY Neon Ice Activity – Combining Crafts & Science

Sometimes the coolest results can come from the simplest ingredients. Here is a perfect example of that! How2PlayToday has shared a step-by-step activity on how to make neon ice. It produces some amazing outcomes, but don’t use it to cool your drink!


Prep: Freeze water in a few different containers overnight.


Step 1. 

  • Empty the ice into large containers.
  • Let the children add salt onto the ice blocks.

Discussion: The temperature at which water freezes is 0 Celsius or 32 degrees Fahrenheit.

Adding Salt to Ice lowers the freezing temperature of the ice essentially causing the ice to melt at a faster rate than if left at room temperature.  This leaves fun little craters in the ice that can be filled with your Neon Water.

Step 2:  

  • In the small containers of water, drop in some fluorescent paint and mix.
  • Provide the children with pipettes and they can drop the glowing water onto the ice (You can also use a paintbrush).

Step 3:

  • In a dark room, bring out your Blacklight and watch as your Ice Glows!
  • The ice is also fun to feel because of the places where the salt as melted it. Go ahead, touch it and see.
