Halloween Anti-Gravity Glow-in-the-Dark Ghost For Kids

This Halloween Anti-Gravity Glow-in-the-Dark Ghost a magic trick. The special-made ghost goes upward, appearing like identifying gravity. it's deceptive and eye-catching. It is a great Halloween science activity for kids to try with their parents.

Age: 3+         Time: <10min

1. Adult supervision.
2. Be careful, the rubber band might beat you.
3. Never look at the black light source in the eye.

 Materials List 
  • Black light source
  • Rubber band
  • Key ring
  • 1 piece of sulfuric acid paper
  • Fish line
  • Two highlighters (green and orange)
  • 1 pair of scissors
  • Pen

Step 1/8 – Draw a ghost on the sulfuric acid paper with a pen and track the pen drawing with the highlighter.  You can also color the whole ghost with the highlighter.

Step 5/8 – Put the rubber band through the ring, grab one end of the rubber band with your right hand, the middle of the rubber band with the left hand.

Step 6/8 – Pull the rubber band tight so that it appears to others to be longer than it actually is. Tilt the rubber band,Let the ring stays near your left hand.

Step 7/8 – Remember to hide the extra band rubber in your fist.

Step 8/8– Constantly and slowly release some of the extra rubber band in your left hand and at the same time, keep the rubber band tight. The ring will move upward to your right hand.

1. Why did my ring slip down?
— It could be that you do it at a big angle. Do the trick in a smaller angle. Always keep the rubber band tight.

2. Why my ring was Vibrating when I released the rubber band?
— Release the rubber band constantly and slowly. It usually takes some practice.

 Scientific Description 
The ring moves due to Elastic deformation of the rubber band and friction with the rubber band.  Elastic deformation is the temporary change in length, volume, or shape produced in an elastic substance by stress that is less than the elastic limit of the substance. In this experiment, the rubber band to extend to a certain length within its elastic limit. After you release the rubber band will slowly return to its original state. The friction between the ring and rubber make the ring unmoved, in relative to the rubber band which is actually moving. Thus the rubber band carries the ring upward.                           

If the rubber band is too much extended, it will break or will not restore the shape. It is beyond the limit of elastic deformation.
Being creative, you can have your own ideas. Check out the experiment of the same principle we did, Anti-Gravity Ring.
