What is a sensory bottle

Sensory bottle is a type of sensory play, which offers a “hands on” approach to help babies make sense of the world and learn to make different connections through play. It is easy to make with endless number of possibilities and creations. Babies and toddlers could learn through playing with the bottles. Also, it could be calming to some babies. They are also suitable for all ages (see this article for some ideas which are related to science for the older children: http://littlebinsforlittlehands.com/5-easy-science-discovery-bottles/)
