3) Bed of nails experiment:
In most magic shows, there is part of the show called bed of nails in which the magician lies on a piece of wood, the size of a bed, with nails coming upwards out of it. It appears to the audience that anyone will lie on this "bed of nails" would be injured by the pointed nails, but this is not so. Today, we are going to introduce how this trick works with no inguries.
This experiment needs some materials to be done under the supervision of the parents.
• A piece of wood
• A hammer
• Nails
• Ballons
The experiment:
•Hammer as much nails as you can in the piece of the wood.
• Blow up a ballon and get it near one single nail which leads to its poping.
• Blow up another ballon and press it to the bed of nails we just made. You will recognize that the ballon doesn't pop easily .
• Increase the number of nails in the piece of wood; then blow up another ballon and press it on the modified piece of wood.
• The ballon will take much time than the first ballon to pop.
