How to Make a potato gun sparker for under $10
This video describes the process of making a potato gun sparker for under $10. Using a sparker replace the butane lighter that most potato guns use to ignite the hair spray. This uses a grill starter which can be purchased for $5 at Wal-Mart. You will also need a soldering iron to make the wired connections. The grill starter is drilled into a PVC cap and then glued permanently into the location. The sparking wire is stripped about two inches to make sure the spark action is sufficient. The PVC cap is then screwed into the potato gun and is ready to ignite the hairspray!
