Vacuum grease
Vacuum grease is a special kind of grease that scientists use when they are working with things that need to stay really clean and uncontaminated.
It's kinda like when your mommy cooks and needs to put oil on the frying pan so that the food doesn't stick. Scientists use vacuum grease to keep things from sticking to each other, but also because it has some other really cool properties.
Vacuum grease is able to handle high temperatures without melting and even in places where there isn't any air. This is important because scientists use vacuum grease to seal things that need to be kept free of air, like a test tube or a valve.
The grease also forms a barrier around the edges of the space, kind of like when you put a fence around your yard to keep your dog from running away. This is important because it helps to keep things from moving into or out of the test tube, which could affect the experiment.
So, in short, vacuum grease is like a special kind of oil that scientists use to keep their equipment clean and working properly. It helps them to do experiments that require precision and accuracy.
