Eggs-perimenting with eggs
What can you do with eggs other than eat them?
Naked Eggs
What does an egg look like without its shell? You may be picturing the white and yolk in a bowl after cracking it, but that isn't the only way to remove the shell.
Materials: an egg, white vinegar, a bowl, a spoon
Directions: Fill a bowl with one cup of vinegar. Add the egg to the bowl, and wait at least 24 hours. When you check it after a day, you'll notice some bubbles on the egg and a residue(残留物) in the water Use the spoon to gently remove the egg from the bowl. Dump out the old vinegar, and add a cup of fresh vinegar. Return the egg to the bowl, and wait another 24 hours. When you remove the egg this time, the shell should be completely dissolved. What remains will be the contents of the egg.
Walking on Eggshells
Can eggs hold the weight of your entire body?
Materials: six cartons(硬纸盒) of eggs, a garbage bag
Directions: Place the garbage bag on the floor to make any necessary clean up easier. Place the cartons of apps into two rows of three. Make sure all the eggs are pointing in the same direction either all pointy end up or all rounded end up. Step onto the first carton of eggs carefully. Make sure your foot is as flat as possible and that you are distributing your weight evenly. If you're careful, you will succeed. Eggs are actually incredibly strong. The arch shape at the top and the bottom of the egg allows pressure to be distributed evenly over the egg. If you were to place the eggs on their sides instead, you'd be likely to wind up with a gooey (胶粘的) mess.
