Whether you’re making a survival-themed short film on a budget or you’re attempting to survive an alien attack, gas masks are an expensive item on your long list of lifesaving tools.
However, with some ingenuity, you can construct a perfectly operational, filtered breathing apparatus using a few items you probably already have around the house.
You’ll need the following: an empty two-liter bottle, an aluminum can, rubber bands, cotton rounds, duct tape, and activated charcoal (which you can find in the aquarium aisle).
First, you’ll need to cut a U-shape out of the two-liter bottle — this will be the mask’s face. Once you’ve cut out the shape, seal the edges with duct tape. The tape will also act as a buffer against cutting your face on the jagged plastic edges.
Next, hold the taped plastic in front of your face to make sure it’s a good size.
Carefully pop a few holes in the bottom of the aluminum can before cutting it in half. After that, place a single layer of cotton rounds inside the cut can. Then, pour in a layer of activated charcoal to cover the bottom. To make sure the activated charcoal remains secure, place another cotton round on top.
You’ve just built yourself a makeshift air filter.
Before duct taping the filter onto the bottle’s open spout, secure one last cotton round to the top of the can — acting as a lid.
Pop a hole in that cotton and then stick the open spout of the two-liter bottle into the slot.
Next, tape the aluminum can to the modified bottle. You can use the rubber bands to help keep the mask on your face as you battle hordes of zombies.
