My kiddo loved assembling the jar! He quickly started asking “Will this sink or float?”. A great activity that promotes language development and sparks curiosity! The jar is leak proof and you must squeeze both handles to twist the lid off! So genius! This water activated sensory light makes for a great night light! We’ve had so much fun reading with it in bed! We love this sensory jar because it offers a calming focus for nap time, bed time, or after big feelings. An excellent calming tool, because you shake and focus on all the fillers. There are several themes for the Fun Fillers, so it makes a great gift idea customized to any kid’s interest!
