In one sentence, describe what the following article is about:

If you decide to buy putty instead of making your own, buy name brand Silly Putty or its off-brand equivalent. Silly Putty can be found at craft stores. Instructions for making silly putty are as follows:  To make silly putty, you'll need Elmer's Glue-All Multipurpose Glue, Sta-Flo concentrated liquid starch, a measuring cup, a spoon, and a mixing bowl. Pour the glue into a mixing bowl. The more glue, the more silly putty. Keep track of how much you put in. For example, if you've got a 4-ounce bottle of glue, maybe you'll want to put in half, giving you 2 ounces of glue in the bowl. Use your measuring cup to measure out as much liquid starch as the amount of glue you used. Then pour that liquid starch into the bowl with the glue. Use a spoon to mix and stir together the starch and glue in the bowl. Let it sit for 5 minutes. After 5 minutes, take the putty out of the bowl. Knead the putty with your hands for 5 to 10 minutes to make sure there are no inconsistencies in the mix. You can find iron oxide shavings at an art supply store. Use your hands to knead the putty until it's a little softer. Stretch it into a flat shape. You can also use a rolling pin to make it stretch further. Do this on a disposable surface, like newspaper or a paper plate. You don't want to be breathing any of the iron oxide. Also, pop on some rubber or latex gloves to save your hands from getting dirty from handling the iron oxide.

Summary:
Obtain or make silly putty. Buy iron oxide. Stretch out the putty. Put a face mask on and gloves on.
