Necessary materials:
- 2 syringes
- the wire
- batteries
- 2 needles from a syringe
Step 1: First, take two needles, and insert a piece of wire into them, and fix them with glue. As pictured.
Step 2: Using a glue gun, glue two syringes together.
Step 3: Dress the needles, and bend the wire, as shown in the photo.
Step 4: Next, you need to bend the needles so that they barely touch each other.
Step 5: Next, take the wire and attach it to the pistons of the syringe. After we do this, insert the batteries and pistons.
And now our portable burner is ready! It will start to work if we close our system by pressing the piston to the batteries.
