Sensory Bottles | AWESOME explanation of the What, Why and How! Start of a new series, MUST PIN!
Sensory bottles! They used Voss water bottles. Not sure where to find them but any water bottle will work. use mineral oil for a way to slow down the materials in the bottle. I usually do 2/3 water to 1/3 oil. Can also do just rice and small objects for I-Spy bottles.
Discovery in a Bottle: I decided to also use the Voss water bottles. It is worth it for the long term use of the bottles. They are very sturdy, no ridges like most bottled waters, and are easier for little curious minds to view what's inside them.
