In this experiment you have to lift a marble without touching it. For this you will need a medium size funnel, a cut plastic bottle and two marbles.
Cut the tube end of the funnel to make a bowl with a hole. This is how the cut funnel will look like.
Now you have to lift the marble off the table without touching it with your hands. For this place the cut funnel on the marble and slowly start rotating the funnel with your hand. The marble will start spinning round and round in the funnel and will slowly rise up. Once you stop spinning the funnel the marble will slowly descend into the funnel hole. Here you can see two little girls performing the experiment.
You can repeat the same experiment with a cut bottle. Cut a rounded plastic bottle about 10-cm from the top. Place the big end of the bottle on the marble and start spinning. As the marble starts spinning in the bottle you can lift the bottle up in the air. The marble will keep spinning in the bottle because of Centrifugal Force.
