2.6 Puzzle time how can you make sure to start a fire with two sticks?
enyata [817]

Answer:

"Make sure one of them is a match"

Step-by-step explanation:

It takes a little practice and above all to generate heat through friction. By raising the temperature of the woods, it is possible to reach the ignition temperature through friction.

Fires require good equipment and good technique. The majority of times it fails is due to a lack of technique and equipment. This can make learning difficult.

For wood selections, you generally want to comply with the following:

  • Dry Tinder
  • You should be able to press the wood. If you can't, then it is too difficult.
  • Wood not very strong but not soft
  • Not sap in the wood

Make the friction forming a 90 degree angle between them, like a cross. Keep one of the sticks supported on the floor vertically, and the other horizontally rubbing it against it at rapid speed, at intervals.

Under this wood put dry tinder that is able to ignite quickly once you generate the fire.

And for the Puzzle remember the orden of the words:

<h2>Make sure one of them is a match. </h2>

Use tree wood, rub and heat until ignition is generated.
