	1 balloon (round ones will work, but the longer "airship" balloons work best)
	1 long piece of kite string (about 10-15 feet long)
	1 plastic straw

	Tie one end of the string to a chair, door knob, or other support.
	Put the other end of the string through the straw.
	Pull the string tight and tie it to another support in the room.
	Blow up the balloon (but don't tie it.) Pinch the end of the balloon and tape the balloon to the straw as shown above. You're ready for...]]></description>

	I know, it's not exactly an experiment, but illusions are still cool.
	Illusions are images that use your EYES to confuse your BRAIN 
	
		
			
				
				
					Take a look at this grid:
					
				
				
				Did you notice the small grayish dots between the black boxes. They are not part of the drawing - they were put there by your brain! Scientists call this "visual vibration." Basically it means that when you see patterns of black and white, your eye sometimes confuses the two and blends them...]]></description>

	A large iron nail (about 3 inches)
	About 3 feet of THIN COATED copper wire
	A fresh D size battery
	
	
		Some paper clips or other small magnetic objects
	



	1. Leave about 8 inches of wire loose at one end and wrap most of the rest of the wire around the nail. Try not to overlap the wires.
	2. Cut the wire (if needed) so that there is about another 8 inches loose at the other end too.


	

	3. Now remove about an inch of the plastic coating from both ends of the wire and attach the one...]]></description>

	A volcano - Talk to an art teacher about making a volcano out of paper mache or plaster. You can also use clay or if you're in a hurry to make your volcano, use a mound of dirt outside.

* An empty soda can
* blown-up balloon
* A head of hair

1. Place the can on its side on a flat smooth surface like a table or a smooth floor.

2. Rub the blown up balloon back and forth through your hair really fast.

3. Now the fun part - Hold the balloon close to the can without actually touching the can. The can will start to roll towards the balloon without you even touching it!
Try This Too: While you've got the balloon out, tear up part of a tissue into tiny pieces about 1/4 inch (.5...]]></description>

* A clear drinking glass
* 1/4 cup vegetable oil
* 1 teaspoon salt
* Water
* Food coloring (optional)


	Fill the glass about 3/4 full of water .
	Add about 5 drops of food coloring - I like red for the lava look.
	Slowly pour the vegetable oil into the glass. See how the oil floats on top - cool huh? It gets better.
	Now the fun part: Sprinkle the salt on top of the oil.
	Watch blobs of lava move up and down in your glass!
	If you liked that, add another teaspoon of salt to...]]></description>

	An old CD or DVD disc
	A 9” balloon
	A pop-top cap from a liquid soap bottle or a water bottle
	A hot glue gu



	If you are using the cap from a water bottle, cover the center hole of the CD with a piece of tape and poke about 6 holes in the tape with a push-pin or small nail. This will slow down the flow of air and allow your hovercraft to hover longer.
	Use the hot glue gun to glue the cap to the center of the CD or DVD disc. Create a good seal to keep air...]]></description>
