🌊Facts about waves: Waves are created by energy moving. Most of the time, this is from wind blowing and disturbing the surface.
🐚 Add to the bottle: Feel free to add any shells or small plastic animals to the bottle.
For this activity you will need:
Mason jar or clear water bottle
Vegetable oil or baby oil
Blue food coloring (optional)
Fill the jar ¾ full with water. Mix with blue food coloring if you have that available.
Fill the remainder of the bottle with vegetable oil.
Add Elmer’s glue to the inside of the cap and seal it tight. Wait for it to dry completely.
To make a wave, tilt and gently shake the bottle. Watch the wave action in your sea. Do not over shake.
⬆️ For older preschoolers: Let them take the reins on this one and let them fill the jar themselves.
⬇️ For younger toddlers: Let your child mix the food coloring in.
