I mad some sensory bottles last night for our baby area at work. It took a bit of experimenting to find out what worked best. I used the following things:
- plastic bottles with screw on lids
- hair gel
- string of beads
- small shark toys
Some of them worked better than others, my favourite by far is the one with te beads in one part water and one part hair gel. Love the way the beads swirl around!
