Here's what you will need:
(1) Roll of black Duct Tape (you can use any color, but black looks pro)
(1) Razor Knife/Box Cutter
(1) package of long stir stick straws.
1) Eat the delicious chippies, savoring each one.
2) After you have devoured one of the best potato snacks on the planet, wash the can in any sink. Make sure to only wash the inside, as the outside has no water resistant coating and will get soggy.
3) Thoroughly dry the inside of the can. You can wrap a paper towel around your hand and shove it in there (if your hands fit) use a hair dryer, or just wait it out. Either way, make sure it's mostly dry in there before continuing.
4) Start at the top, place the edge of your tape along the lip of the can where the top usually goes. Wrap the tape down the entire can. You COULD just spray paint the can, but the tape adds a layer of durability in addition to sleek looks.
5) When you get to the bottom, cut the tape with your razor knife.
6) Now, this step will be different depending on the size of your flash head. I have different flashes, so I used both methods (see pictures below)
a) If your flash head looks bigger or as big as the can: Using your razor knife, cut the bottom of the can off. Cut four 3" strips of tape, fold the tape on each side of the bottom of the can. You want about 1/2 inch of tape on the inside, and outside of the can. This will leave four flaps on the bottom of the can. These flaps will help keep the stray light from leaving the can when your flash goes off. To insert your flash, simply press on the top and bottom of the can to make an oval, insert flash head, release.
b) If your flash head looks like it could fit easily: Hold the bottom of the can to your flash head and trace with a Sharpie marker. Use your box knife to cut a horizontal slit in the rectangle you just drew, then cut horizontally down the sides. Cut the sides completely out, and fold in the top and bottom.
7) Optional: fill the can as full as you can with your straws. When it's full, carefully pull them out halfway, wrap some tape around them. Hold the circle of straws as tight as you can and wrap tape around the straws as tightly as possible.
