Akhar

So, I have a combustion engine to power my fuel loader for my rocket, which I had running to fill it up. I then launched for the moon. Later, my sister told me that my setup was blowing up. So I ran over to her computer, and my combustion engine had exploded. I had left it on like an idiot, and now it's exploding infinitely and I have no idea how to stop it. Any ideas?
