3. Classroom Microgravity Demonstration To demonstrate microgravity in free-fall, poke a small hole near the bottom of an empty soft drink can. Cover the hole with your thumb and fill the can with water. While holding the can over a catch basin on the floor, remove your thumb and observe the water stream. Reseal the hole and refill the can. This time drop the can into the basin and watch to see if the water streams out of the hole. What happens? Why? (Recycle the can after you are finished with it.)

11. All these toys are different in space because of the gravitational acceleration.
