【题目】How to DIY Your Own Mask

During the outbreak of COVID-19, one of the must-have items is the mask. However, many countries are in bad need of medical masks and other protective equipment. 1 But we can make our own masks which can be used repeatedly. Now, let’s look at the most popular DIY method for soda bottle gas masks.

2 And it doesn’t require huge skills. With necessary materials and a little training, it can be made in 15 minutes.

To make such a mask project, you’ll require a sharp cutting tool, a market, glue, a 2-liter soda bottle, rubberized foam insulation strip (泡沫橡胶绝缘条) and one N95 mask. Total cost may be $5.

First, you’ll have to clean the 2-liter plastic bottle. After that, draw a U-shaped area using the marker. 3 Then start with a smaller cut and work your way up from there. Cut away the bottom of the bottle and you’ll end up with a basic shape.

Next, use the rubberized foam insulation as a seal for the edges of the bottle. 4 This will serve as a resting place for the N95 mask. Then cut off the N95 mask’s edging carefully. And place is inside the neck of the bottle. The elastic bands (橡皮筋) from the N95 mask will be used to secure the gas mask firmly on your face. Then a DIY gas mask is completed.
