Question

	Ping Pong Door Do you want a ping-pong table in your room? But you may not have enough space. Now this door is here to help you. It can turn into a ping-pong table when you pull it down. After the ping-pong game is over, it goes back to being a common door. It was designed by Tobias Fr?nzel from Germany. Cool idea!
	Dog Watch The dog watch is a “clock for keeping time at a rate(比率) other than human time” and was invented in 1991. With this watch, you can know time at your animal’s rate instead of your own. The watch multiplies（乘）every human time by seven, giving us “doggy time”. If a dog lives to be the age of 14, that translates into 98 human years!
	Earthquake House Big earthquakes can hit a house, possibly making the people in it get hurt. But Dysinger has found a way, the Earthquake House! His idea is simple. Build a round house that has earthquake sensors(传感器) in it. If the sensors know the big earthquake, the house is free from its chains(链条). Don’t worry. You always remain straight in it.
	Smell This How do you know if your breath smells nice, or if it smells bad? It’s difficult to know because it’s very hard to smell the air that comes out of your own mouth. Smell This is useful for this situation. You just place the mask on your face, then breathe out through your mouth and breathe in through your nose.
