What’s new in the scientific community? Here are four gadgets(小玩意儿)to open up your eyes:
Mosquito Repelling Necklace
For quite a lot of people, mosquitoes are one of the biggest problems brought by the warm and often rainy season.The necklace generates a sonic(声波的)repelling frequency(频率), which keeps the insects away.Unlike many other products, it doesn’t use any kind of chemicals and toxic sprays that poses a potential threat for the human body.The plastic case is compact(简洁的)enough to wear around your neck or clip to your collar.Effective up to three meters in radius(半径).
Ice Cream Ball
Ice cream in just 20 minutes? No magic tricks.
All they’ll need are five ingredients and some rolling around.Load ice and rock salt into one end and the ice cream ingredients into the other.As the mixture of ice and rock salt is melting, it absorbs heat.
Roll or toss the ball around and voila(那就是)-ice cream.
Cell phone
This new kind of cell phone features a color touch-screen-speech balloons(对话框)are brought to real life from comic(漫画的)strips.It adapts to your favorite comics:talks to you in your favorite character’s language, updates you on new ringing tones and games based on the comics.The tail of the cell phone serves as a Usb.connector to interchange data between this phone and a computer.Turn this cell phone 90 degrees-the contents of the screen will rotate(旋转)as well.Even if you hang upside down like Spiderman you will make everything out.
Time-flex
Want to keep track of time but hate wearing bulky watches? Check out Time-flex, this ultra-flexible, self-gumming watch sticks to your skin or clothes like a transparent Band-Aid.It can be peeled off and rolled up like paper when not in use.You control the menu via touch-screen.It’s powered by ultra small batteries that are invisible to the naked eye.
