I stretch as far as a football field,
Yet I fit in the palm of your hand.
I will make you bleed if you don’t use me often.
You put me in your mouth but don’t eat me,
Then you throw me away.
Floss. It typically comes in 100 yard packs, which fit easily in your hand. If you don’t floss regularly, your gums will bleed. You use floss in your mouth then throw it away when you’re done.
If a cork is placed into a glass of water, it will almost always drift to the side of the glass. There is one simple way, however, to get the cork to float in the center of the glass. What is it?
Water, the glass, and the cork are all that is required.
The reason that a cork drifts to the side of a glass is that it floats to the highest point. Since water “clings” to the glass, the highest point is around the edge of the water. To get the cork to float in the middle of the glass, all you have to do is fill the glass as much as possible. The water will form a convex shape above the glass, with the highest point at its center. This is where the cork will settle.
You have a fox, a chicken and a sack of grain. You must cross a river with only one of them at a time. If you leave the fox with the chicken he will eat it; if you leave the chicken with the grain he will eat it. How can you get all three across safely?
Take the chicken over first. Go back and bring the grain next, but instead of leaving the chicken with the grain, come back with the chicken. Leave the chicken on the first side and take the fox with you. Leave it on the other side with the grain. Finally, go back over and get the chicken and bring it over.
I torture children and parents
Many people scream and wail in my presence
Parents drag their kids to me
I am supposed to create smiles,
But often there is only a frown.
