Liquid Bubble Timer
If you're into visual stims, this might be the stim item for you! These hourglass shaped fidgets are filled with beautiful colours.
These fidgets don't require constant effort or supervision on your part to work. Just turn them over and watch the different bright liquids drip, mix and flow together to slowly gather at the bottom over the course of about three (3) minutes. Then flip it and they'll start it all over again!
Measurements are approximately: 15cmx5cmx2cm
