HONOLULU (HawaiiNewsNow)- The one and only Dr.V from Oceanit Hawaii is back! He shows Taizo how to use a glass cup to spin a marble! Check out the video!
Dr. V Show: Spinning Marbles
Things you will need:
- Glass with a mouth narrower at the top than the bottom
- Small ball
Please to do this and all other experiments under the supervision of an adult. Place the marble or ball on a table top and trap it under the glass. Start wiggling the glass so that you get the marble to start rolling around the rim of the glass. As you get it spinning faster, what happens to the marble? Once you've got your marble spinning pretty well in the glass, lift the glass off the table. What happens to the marble?
How does it work?
