Going to college these days means that you are almost assuredly carrying some electronic gadget with you in your bag or backpack at any given time. A particularly expensive and likely highly beloved gadget at that. So what if you get caught in a sudden snowstorm, or if you, like me, live in a place where it only stops raining for two months out of the year, and you don’t have a waterproof bag? Instead of buying a ridiculously expensive gore-tex backpack, why not try and waterproof the one you already have? Luckily, the folks over at DIY Photography have found an easy way of securing your canvass bag and keeping your electronics safe from rain, sleet, or snow.

To do it, all you need is a double-boiler (one pot filled with boiling water with another pot sitting directly on top), a mixture paraffin and bees wax, and a brush.
According to DIY photography, it’s best to try this without using your regular pots due to how potentially messy this project can be, and recommends using camping equipment or old coffee cans. Once the water has begun to boil, place the wax mixture inside the top pot and allow it to melt. Then, use the brush to coat the wax over your bag or backpack. After you’ve covered every inch of the bag, let it dry until the wax has become hardened and caked. Finally, toss the canvass bag into an old pillow case and tie it off before puting it into the dryer on high for 15 to 30 minutes to help melt the wax evenly over the bag.
