<human>: Provide a brief overview of the text.

This happened some months ago. A few friends and I (all high school students) decided to embark upon the process of creating a 3D printed homemade rocket using rocket-candy (A Potassium Nitrate mixed with caramelized sugar mix) as the propellant. Creating the parts was no big issue, and we had everything printed in no time.

On a bright Saturday morning we decided to create batch of rocket-candy at my friend's house for a test-fire that we wanted to do in the rocket later that day. It wasn't our first time creating the fuel -- We had prepared a few batches in the past and had set them off without any issue. I guess screw up #1 was that we  decided to make about twice as much as usual per batch. 

So I was outside in the yard, trying to scrape a bunch of white powdery chemicals with sugar and trying to get the latter to caramelize. My friend's mom came out and offered to help while I went and helped out with some other friends. So I ran off to the other side of the yard while she took the pan inside... screwup #2

2 minutes later, I hear a shout and look inside the kitchen window. I'm greeted by a wall of flame as high as the ceiling and a *ton* of black smoke everywhere. I promptly proceed to yell a bunch of curse words and then run inside to help put out whatever had started.

Thankfully the fiasco had mostly been a smoke bomb, but it left a few marks on the ceilings and my bowels on the floor. 

What made it worse is that we had been sternly instructed not to cook inside the house, in fear of the fuel going off....

Turns out my friend's mom had thought I was only caramelizing sugar, and thought it would be safe to take it inside to finish over the stove. oops.
<bot>: Friend's mom thought I was cooking sugar instead of rocket fuel, I forgot to clarify --> pound of rocket fuel going off in the kitchen
