Sensory bottles are fun to make and can be a calming tool.
All you need is:
1. A clear empty bottle
2. Distilled water
3. Glycerin (available at pharmacy stores)
4. Glitter flakes, sequins, light plastic beads, or other sparkly things that are light enough to float around
5. Some lace, twine, or sequin string to wrap around the neck.
NOTE: You may want to glue down the bottle cap or cork to better secure it.
