FLOATING EGGS

For this experiment you'll need the following items:

• 3 glasses filled with 250 cm3 of water

• 3 eggs

• a lot of salt
• more water

In the first glass, put the first egg. The egg will sink (not sing... aha hah)

In the second glass, add 4 full spoons of salt. Stir very well.
Put the second egg in the water.... It floats at the surface!

In the third glass, add 4 full spoons of salt. Stir very well.
Put the third egg into the water. It floats like the second, obviously. But now, watch the video...

CANDLE SUCKING UP WATER

For this experiment you will need the following items:

• A pan
• Water
• A glass
• Two nickels
• One candle
• Matches

Take the pan and fill it with 1/4 of water.

Take the 2 nickels and put them in the center of the pan,so that the glass can lay on them, and still have space for the water to flow underneath. 
Then take the candle and put it in between the two nickels.

Light the candle.
Put the glass on top of the candle, sitting on the two nickels.

Observe what happens.

HOW TO MAKE A ROCKET

To make a rocket, you will need the following items:

• An empty bottle (a seltzer bottle)
• Baking soda
• Vinegar (white vinegar)
• One tissue
• One cork that fits exactly the bottle opening so no air can get out
• A plank of wood
• One screw

Take the piece of wood and screw the cork to the plank of wood.
Now, take the tissue and pour a lot of baking soda in the tissue. Then roll the tissue up like a crepe and fold the two ends.
After that, fill 1/8 of the bottle with vinegar.
Put the "crepe" inside the bottle.
Put the cork that is screwed to the plank of wood on top of the bottle.
Turn the bottle upside down quickly and make sure the bottle doesn't fall over.
Run away ... but not too far :-) I just mean that you shouldn't lean over the bottle as it's going to...

Now watch your rocket fly!
