This is a hint for the game White House Escape. Please be warned, the following hint gives information that could be considered a spoiler. For this reason, we would like to caution you about reading the hint unless you are certain that you want to proceed with knowing the information contained herein.
You've done well - you have explored the White House Residence, and now have in your possession a flash light. However, the flashlight is dead, and of not much use in its current condition. Luckily, it is one of those flashlights that do not use batteries - you only need to shake it to charge it up. Unluckily, though, no matter how much shaking you do on your own the light will not charge enough to shine (it must have been left on during someone's midnight trip through the halls).
So, how do you charge it up? Well, in your explorations you may have come across a large mixer. The mixer has a dough attachment on it, which would serve to shake and knock around something placed in its bowl. This is how we can charge our light. Use the light with the mixer, it shakes our light much faster than a person shaking it by hand could. The flashlight comes out a bit scuffed but shining. Now we need to find a nice dark place to use it. But be warned - the flashlight charge has a limited life span, then we will need to repeat the process (if we haven't finished with it by then).
