Ideas for how to use certain elements in creative way.

In my Magic system, one of the type of magic manipulation is called Distortion, which is, as its name's implies, allow the Distorter to change one of four elements around them : * Space * Gravity * Void * Time

I have come up with a lot of ways someone could Creatively uses those Elements, such as using Void to create an infinite freezer for food, as time doesn't pass in a Void, or using Gravity to fly and hit people harder. What are some ways you think someone could use those elements ?
