Step 1: What You Will Need.
2 - Some electrical tape.
3 - A "Bubble Stick" ( from Walmart $0.68c )
4 - A saw; lighter and knife.
2 - Cut off the screw end of the Bubble stick, wash and dry the tube.
3 - Clean off the burrs with a knife then use a lighter to smooth the jagged edges ( just repeatedly flick the flame over the edge and round it inwards with your fingers )
2 - Use some electrical tape to hold it in place.
Step 4: Lightsaber.
An extra add-on is to remove the strap that is on the mini flashlight and replace it with a hair rubber band. ( this is great for spinning it around, as the strap did not last long )
Have fun making one.
