My kids love sensory play and today they decided to get a tad crazy with their quiet time activity by mixing their two favorite sensory bin materials – Water Beads + Slime. Playing with this slime was so much fun and learning How to Make Water Bead Slime was an adventure in itself!

This has been the stretchiest slime we have made. How the waterbeads and slime acted together was fascinating!

NOTE: Other brands of glue will not work as well as Elmer’s Glue will.

How to Make Waterbead Slime

To make this slime, you will need about 45 minutes due to the time it will take for the waterbeads to absorb the water. What I did for this was open my glue and put it into the first container upside down to let gravity help empty the bottle. In my second container, I filled it with water and dumped in the waterbeads. Both of these containers were then set aside for about 15 minutes.

After about 15 minutes the waterbeads should have absorbed enough water to expand, but not expand fully. When they are completely expanded they will be smooth. For this slime, you will want the waterbeads to be bumpy, they will absorb more liquid once mixed into the slime.

To make the slime you will mix in one tablespoon of liquid starch at a time until the slime no longer sticks to your fingers. I know this picture is difficult to see with the white on white, but it should look close to this once ready.

Stretchy and not sticky. Once at this consistency move your slime out of the bowl and over to your crafting tray. Then dump in the waterbeads…

and smush, smash, and mix them in! My son had a blast with this.

The slime was SUPER stretchy.

We were able to make it stretch from the ceiling to the floor without it breaking! Meatball had a blast trying to see how wide he could make it stretch.

He almost got it wrapped around himself. He also explored how small he could make a slime ball. When squeezed it popped loudly!

Some of the waterbeads broke apart creating a fun confetti look. Meatball had a lot of fun exploring what the insides of the waterbeads looked like and what they felt like to squish.

The coolest thing ever happened not during play, but after. As the slime sat on the tray untouched it began to bubble. And as the water beads grew in size those bubbles got even bigger! This slime was perfect for discussing surface tension!

Which of course led to us picking this slime back up to play with again!
