Wool scarf
Begin this science trick by mixing salt and pepper on a flat surface. Ask your audience if they think they can
separate the pepper from the salt with a plastic spoon. If someone volunteers, let him try for a few seconds (but don't
be too hard on him). Then, pull out the wool scarf and rub the plastic spoon quickly back and forth upon it. Next, hold
the spoon about ½ in.-1 in. above the salt and pepper mixture. The pepper should jump up onto the bottom of the

Why Does This Happen?

When you rub the plastic spoon, it gains a static charge, which attracts the pepper. The salt is also attracted, but
because it is heavier, it cannot rise like the pepper.

The Jumping Coin

Items Needed:

Glass soda bottle with a small mouth
Coin, slightly larger than the bottle's mouth
Begin this science illusion by placing both the empty soda bottle into the freezer.  Next, take both items out of the
freezer, and place the coin on top of the bottle top. Now hold the bottle with both hands and watch the coin move
(Sometimes it takes a minute or two.  Make sure the coin completely covers the mouth of the bottle.  The coin should
look like it is jumping up and down on the mouth of the bottle.)

Why Does This Happen?

When the bottle and the coin are placed in the cold, they both become cold. When you hold the bottle in your warm
hands, they begin to warm both the bottle and the air inside it. When the air gets warmer, it moves around faster and
pushes up on the coin at the mouth of the bottle. Because of this, when the air cools down, the coin stops jumping.

The Toothpick Triangle

Items Needed:

Four (or more) flat wooden toothpicks
Bowl of water
Dish detergent
Carefully place three toothpicks onto the surface of the water so they touch one another in the shape of a triangle. It
may take some practice to achieve this, but the toothpicks will float in the design of a triangle when placed correctly.
Once you have accomplished this, dip one end of the fourth toothpick into dish detergent. (If you are doing this to
baffle your friends, you should have the fourth toothpick already dipped in detergent prior to their arrival and set

To achieve the science trick, touch the soaped end of the toothpick into the water in the middle of the triangle. The
toothpick triangle should break apart when the fourth toothpick touches the water.

Why Does This Happen?

All things created are made up of molecules. The water molecules in the bowl stick together to form an invisible layer
on the surface called surface tension. It is the surface tension of the water on which the flat toothpicks float. When
you touch the toothpick with detergent into the water, the soap molecules break the surface tension. The breaking of
surface tension pushes the other toothpicks out where the surface tension has not yet been affected.

Once the soap molecules are introduced to the bowl, the surface tension will not come back. If you want to repeat
this science trick, you will have to rinse the bowl out and use new toothpicks.

Invisible Inks

Items Needed for Ink 1:

Lemon juice
Cotton swab or small paintbrush
Warm lightbulb, warm oven, or other heat source
To create Ink 1, write a message onto the paper with lemon juice. Allow the juice to dry completely. With your
parents' consent, hold the paper close to (but not touching) a warm lightbulb to make the message visible.

Why Does This Happen?

Lemon juice is acidic. When the acid is heated up, it darkens more quickly than the paper.

Items Needed for Ink 2:

Baking Soda
Purple grape juice concentrate
Cotton swab or small paintbrush
To create Ink 2, mix equal parts baking soda and water. Using this mixture, write a message onto the paper. Allow
the paper to dry completely. Next, paint the paper with grape juice. Your message should not be invisible any longer.
