Recently we tried making sensory balloons & painting. I see Play At Home Mom recently posted about a similar activity using filled balloons as a sensory activity.
Sensory Balloons & Painting
Our balloons were filled with flour, rice, pasta, salt, water and corn from a sensory bin.
The kids really enjoyed guessing what was in each one. The flour and water were especially enjoyable to manipulate. After playing with them and guessing what was in each balloon, we made paintings.
