Create a calming ocean-themed sensory bottle for kids using water, shells, glitter, and blue food coloring.

One lightweight plastic bottle (empty and clean, with a tight-sealing lid)

Water

Small seashells

Small decorative starfish (plastic or craft-safe)

Blue food coloring (optional)

Glitter (optional)

Small plastic beads or gems (optional)

Clear hair gel or baby oil (optional, for slowing movement and enhancing visual effect)

Hot glue gun or strong tape (to seal the lid securely)

Start with a clean, empty plastic bottle that has a secure-fitting lid.
Fill the bottle about three-quarters full with water.
Add a few drops of blue food coloring if you want to create an ocean-like appearance.
Gently place seashells, small decorative starfish, and other sea-themed items like beads or gems into the bottle.
For added sparkle and texture, sprinkle in a little glitter.
Optional: Add a bit of clear hair gel or baby oil to thicken the liquid and slow the movement of the items inside.
Once all desired items are added, top off the bottle with water, leaving a small space at the top to allow for movement.
Secure the lid tightly. For safety, seal the lid with a hot glue gun or wrap strong tape around the cap to prevent leaks.
Shake gently to mix, then let kids enjoy watching the sea-themed items float and swirl inside.

Personalize with toy fish or colored sand. Always supervise children while crafting. Inspect bottle regularly for leaks.
