That may give you a tiny bit of power. Take the battery from the phone and rub it between your hands. Or warm it under your arm for a few minutes. Then try to start the phone – but use it quickly. ● What to do if your gadget gets wet First, try drying it out with a vacuum cleaner. If a vacuum cleaner isn’t at hand, fill a pot or bowl with uncooked rice and put your we gadget inside. The dry, uncooked rice will absorb all the water and, after a few hours, you should be able to use the gadget. Don’t forget to remove the battery and SIM card before you dry it. ● What to do if your TV remote control stops working If replacing the batteries doesn’t work, get the camera function up on your phone and point the remote at the lens(镜头). When you press a button on the remote, if it's working then the glass bobble(小球) at the front of the remote will light up when you look at it on the screen of your phone. This is because the screen on a phone or digital camera picks up infrared rays (红外线), even though your eyes don't. If the glass bobble doesn’t light up, the remote is broken. If it does, the receiving device is broken. 43．If your cell phone falls into a sink, you can         . A．warm it up under your arm.       B．put it into the uncooked rice.
