Introduction: Don't Leave the Stove On!
Too many times I have gone into the kitchen to see that SOMEONE left a burner on the stove running! Time to solve this problem.
Step 1: The Problem
At a quick glance, when the dial is straight up and down, it looks like the burner is off, but it's not!
Step 2: Solution
Add a piece of red duct tape to the bottom of the dial, so when it is straight up and down you see that it is indeed left on.
Step 3: Solved!
Now it's easier to notice that the burner is still on.
