Tired of constantly replacing your sensory bottles, the Fun Science Jumbo Sensory bottles are your solution. These large non-breakable and reusable bottles stand on their own. Each bottle holds up to 100 ml of liquids and is large enough to slip any large object inside to observe. Hot glue the lids to seal then flip it over and allow it to stand on the lid. These won't fall over easily. Bottles come empty with an activity guide with ideas on how to create you own fun. The Jumbo Sensory Bottles are a great addition to the sensory section of your science center (The set includes five empty jumbo sensory bottles). Scientific Skills: Experimenting, Observing, Exploring and Drawing Conclusion.
Awesome quality!
