Question

【题目】 A woman in a lab coat stands in front of a group of school children. As she pours hot water into a box of liquid gas in the front of the classroom, the children cheer and clap their hands.

The woman is Kate Biberdorf. She runs a program called Fun with Chemistry which is aimed at getting children interested in science. The demonstrations(演示), such as the one she has just finished, are designed to be interesting and exciting and show children basic rules of chemistry.

Most of the demonstrations involve “explosions(爆炸)” and “fire” which are wonderful to watch. One of the demonstrations is called “Elephant's Toothpaste.” Biberdorf creates some foam(泡沫) that increases very quickly in size in the classroom. There is so much foam that it seems as if the foam can be used to clean the teeth of a big animal like an elephant. In another demonstration, Biberdorf makes a fire on her hand and sets a balloon on the fire.

There are also demonstrations designed for certain festivals. For example, Biberdorf uses pumpkins on Halloween. She pours some liquid into a pumpkin. The liquid then explodes inside the pumpkin and makes holes on it. The final product is a jacko'lantern(南瓜灯) with two “eyes” and a “mouth” made by the explosion.

Biberdorf and her program are popular among school children. She_is_happy_when_children_tell_her_how_excited_they_are_after_watching_her_performances._ She is encouraged by their words and is designing more performances. What a great teacher!
