How to play

Fill a small mason jar about three-quarters full with water.

Add a few drops of natural food coloring and a tablespoon of rice or dried lentils.

Seal the lid tightly and wrap with strong tape for extra security.

Hold the jar and slowly tilt it in front of baby, let them watch the swirling colors and tumbling rice.

What you need

• Water

• Natural food coloring

• Rice or dried lentils

• Strong tape

Simple household items. No plastic toys needed.

Why it works

Sensory jars captivate babies with slow-moving visual stimulation, building focus and calm attention. The weight of a glass jar also provides grounding sensory input.

Good to know

An adult should always hold the jar, do not let baby hold or drop it. Tape the lid securely. Use a small jar (half-pint) so it's easy to manage. If you prefer not to use glass, a stainless steel water bottle with a clear window works too.
