Making Water Bubbles
Ask the child to place her hand under running water and move it out in around 5 sec. You can observe tiny water bubbles on the hand that vanish away in a while.
Touch the bubbles.
Repeat with another hand.
Touch the bubbles.
My child loves making bubbles whenever I take her for cleaning up after a meal. And then, she tries to stop the water flow by holding her palm tight against the tap opening, the water spurts out, she laughs.
