Little hands will LOVE this!
Help them mix up some homemade Gak and get their hands into this gooey-gloppy slippery mess for a sensory experience like no other!
The more they knead it the firmer it becomes…. and they will learn about CHEMISTRY and what a POLYMER is too!
Here’s the recipe:
- school glue
- Borax mixture (mix 1 teaspoon Borax laundry booster into 1/2 C. warm water)
- food coloring (if desired)
- small cup
Pour glue into a bowl (1 school glue size bottle for an individual batch). Slowly add Borax mixture to glue- USE YOUR HANDS to mix!
The glue will absorb the Borax mixture causing a CHEMICAL REACTION and creating a polymer.
Continue adding Borax solution to the glue until no more is absorbed (you can pour off any extra Borax solution).
Store your Gak in a ziplock baggie or plastic container. As it ages it will change from a super slippery wet substance (day 1 at the beginning) to squishy soft goo (day 1 after it’s squished for a while)…. to a firmer Silly Putty type substance.
Children can see how 2 liquids (glue and Borax water solution) react to create a POLYMER.

Here are some great reasons to make Gak:
- hands-on chemistry EXPERIMENT
- SENSORY play (wet & squishy)
- self-regulation (CALMING and centering to squeeze and feel)
- FINE MOTOR strength & dexterity (roll, squeeze, pinch, twirl, poke…. to strengthen little hands and finger
What to do when the Gak gets a little bit firmer:
- early scissors skill practice (roll Gak into “snakes” then cutting using scissors)
- hide small beads or buttons in the Gak for little fingers to dig for TREASURE! (great fine motor strengthening too)
Enjoy & have FUN!
