5 Minute Science Lesson - The Punctured Bag

You need: A polyethylene bag, some ordinary pencils, water.
The experiment: Fill about half the polyethylene with water. Pierce the bag using the pencils in the places where it's filled with water.
Explanation: If you pierce the bag with the pencils and only then pour in the water, it will seep out through the holes you've made. But if you fill it first and then insert the pencils, the water will not seep out at all. This is a result of the fact that when the polyethylene is broken apart its molecules move closer together. In this case, the polyethylene tightens around the pencils.

5 Minute Science Lesson - Shadows

You need: Some matches, a flashlight.
The experiment: Light a match and hold it about 2-3 inches away from the wall. Shine a flashlight over your hand holding the match. You'll notice that only the shadow of your hand and the matchstick itself will appear on the wall - the flame will not appear.
Explanation: Fire does not produce a shadow, because it doesn't impede the passage of light through itself in the same way that physical materials do.

5 Minute Science Lesson - Waterfall

Do you know what this is? It's a waterfall. Where do you think the water is coming from? Where do you think the water is going? Would it be safe to stand at the bottom and let the water fall on you?
