Here is a list of the devices you have access to. Note some of these you can only use once. The ones with the black balls next to them can be used many times, but after the first time the text will vanish. If the device asks you a question, don't lie, otherwise you lose some of the fun. It will know what to do, so you don't need to in reality read the instrutions.
