How to make it
Check the cap before every play. Oil is slippery if it leaks.
1Add the water
Fill the bottle halfway with water. Add 2 drops of color.
2Add the oil
Fill the rest with oil, leaving 1 inch of air at the top.
3Seal the cap
Grown-up step: Run glue around the threads and twist the cap on tight. Let it set 1 hour.
4Tape it
Wrap tape around the cap for a second seal.
5Tip and watch
Show your toddler how to tip it slowly and watch the blobs slide.
Keep it in a quiet corner for when they need a minute.
