Colored Flames for Cigarette Lighters
Imagine something besides the same boring lighter colored flame of blue tipped with some yellow. Since all fireworks come in all colors, then we are able to add all or some of the colors of choice from metallic compounds in a flexible metal strip loaded into a roll, and would come up with the rolling of the wheel on all lighters and change the color of the flame and burn up with it.
You might imagine adding colors to all lightables such as matches or just about any flame or flamable. It would take very little flame and could be a rainbow of your choice of color or color combinations depending on the burnable metallic compound or compounds used.
Reward: A multi-colored lighter and fun for every one!
