STEM Grab & Go Bag: Sensory Bottles

This week we’re exploring liquid density with sensory bottles. Sensory bottles (or discovery bottles) are simply empty bottles filled with various materials. They make a fun sensory play for children of all ages and can even be used to encourage quiet time with children. They’re really mesmerizing to look at! You’ll need some super glue (or similar) to seal the bottles closed once filled, otherwise all supplies and instructions are included. For chemists ages 3+ although younger ones will need assistance.
