Wow-To:

Step 1: Gather up any masks you’d like to test as well as all other materials needed for the experiment. We recommend testing between 3 and 6 masks.

Step 2: Set up your testing zone by clearing a table or counter of any clutter. Make sure an adult is available to supervise you as you will be dealing with fire.

Step 3: Light the candle or help a grown-up light the candle.
Step 4: One by one you will test each mask by holding it up to your face and trying to blow out the candle through the mask. Record results for each trial.

 

Step 5: Review the data. What do you notice? Were some of your masks more effective than others?
