This is hands-on physical science at its best! The translucent casing lets children see the pumping mechanics in action. It looks like there's nothing inside, but press the pump and feel the blast of air as it shoots out the end.
This lightweight pump is easy to manipulate yet really durable and hardworking. Use the needle tip to inflate playground balls and the plastic tip for beach balls. Instructions included. 12" long; extends to 19½" long. Assorted translucent colors. Ages 5 and up.
Please note: This pump is suitable for use for Activities with Gas - Air: "Air - Pump It!" and "Air - Balloon Fun" in Meg Fedorowicz's book Nurturing the Young Scientist (SC413).
