Water Beads 💦 ages 3-8 💦 These little beads are so amazing and great for sensory play! They come in a tiny bag and you soak a small amount in water for about 8 hours and they expand to the size of a marble. Put the clear ones in water and they become invisible. So cool! You can order on Amazon though this link (aff. link) http://amzn.to/2oCMPJTÂ
