(It doesn't really start a fire, but it will ignite easily which will assist you in making an awesome fire!)
Step 1: What You Will Need
1 Toilet paper roll and Lint from a dryer
Step 2: The First Step
Put the lint in the toilet paper roll! (Don't pack in the lint to tightly, it will not ignite as easily!) Also, leave a little bit of lint sticking out.
Step 3: Now Light It!
You can use it to help with a camp fire or in a backyard fire pit! Just light the part of the sticking out lint with a lighter, matches, etc.
