The science behind my reusable water balloons

Reusable water balloons are such a great way to entertain your kids over the summer and keep them outside and enjoying the sunset! However, it may seem a bit weird to use these reusable water balloons instead of normal ones, so I want to share a bit behind how the material works!

Science behind Reusable Water Balloons

My water balloons are made of a special type of yarn called chenille yarn, which means that it's a big thick yarn with lots of tiny strands sticking off the main, center thread. This means the water gets trapped between the small yarn strands, letting the balloons absorb water.

The yarn is made of 100% polyester yarn, which is a hydrophobic material. Hydrophobic means that it repels water, so this yarn doesn't want to hold onto the water, making it easy to squeeze the water out of the yarn!

Combining these two factors means that the yarn can hold water between the tiny little strands but doesn't hold onto it tightly, so it squeezes out when it hits something!
