Attach the water lab to the tub with the suction cups, fill the test tube with water – with or without the help of the metered marks of measurement on it – and pour it into a funnel. Then watch the mysterious effects unfold with just the power of water!

Pour water into the detachable funnel and set the googly eyes into motion.

Pour into the other funnel and set the dial spinning.

Watch the water flow out from beneath the dial and magically spring out from the 10 holes in the pipeline.

Point out to your child the chain reaction as the lab is activated.

Follow the stream of water as it flows out from under the googly eyes, from one side of the pipeline to the other, and spins the propeller.

The water lab attaches to the tub for easy play and storage.
