This was such a fun activity that I thought I’d share! We made these four different sensory stress balloon balls out of typical everyday fillers. You have to first fill a container with a small spout with the filler — we used salt, flour, sushi rice, and oatmeal. I didn’t double layer the balloons, but I’d highly recommend that so that they last longer. Then blow up the empty balloon and while holding the air in, wrap the neck around the bottle spout. Turn the bottle upside down and let the filler fall in. The thicker the filler, the more you will have to coax it through the neck of the balloon. Then take the balloon off and tie it and voila! Sofie loves squeezing these and playing with them whenever she’s frustrated.
