That's right, it's time...time for more silly faces with Peko Lux! Peko makes funny faces, rolling her eyes, and new to this video, uses a spirometer! If you don't know, a spirometer is "a diagnostic device that measures the amount of air you're able to breathe in and out and the time it takes you to exhale completely after you take a deep breath." An affordable and useful tool if you are paranoid about your lung function! It's also good for exercising your lungs, as Peko does here, while making funny faces!
