These discovery jars are my little take on a discovery bottle, sometimes known as a sensory bottle too. They provide a safe way to present small objects to babies and young children as they can get a close up view of things that they would otherwise pop straight into their mouths. They can also provide other sensory experiences like interesting sounds and soothing visual effects.
These particular jars appealed to me for many reasons. They are made from plastic so they are safe if they are dropped and it also makes them light to hold. The lid too is clear plastic and this makes it very easy to see what is inside from many angles. They also stack on top of each other, and with a slight twist they lock into place, this aspect makes it especially fun for older children too.
The jars will be found in the craft storage section of your craft store, I bought these ones at Spotlight.
To secure the loose objects safely inside the jars and to prevent leakage from the containers with liquids I hot glued the lids into place. Using hot glue meant I had to work quickly to twist the lids closed before it cooled. I think next time I might use a silicone sealant from a hardware shop, this will specifically help to keep the liquids from leaking out.
