As you move closer to your science machine, keep an eye on square pictures that go down the left-hand side of your screen. When some new ones light up (food, for example), you know you are standing close enough to use the machine. If any of the squares have a light bulb, that means there are new things in that category that you can prototype. Click the square to get a picture list of what's available and what is still locked for each category.
