We made DIY bounce balls using just a few simple ingredients, and it was such a fun little experiment! Even the making process turned into an amazing sensory activity — my daughter loved squeezing, shaping, and forming the ball in the water with her hands. From this amount, you can make a few bigger bounce balls or several smaller ones, however you like — it’s completely up to you. Recipe: • In a medium bowl, dissolve 2 tbsp borax in 2 cups warm water • In a separate bowl, mix 1/3 cup white glue
