You can make a tiny cloud using just your mouth. First, breathe in through your nose and close your mouth to trap warm humid air inside. Then, click your tongue against the roof of your mouth about 20 times with your mouth closed - each click launches microscopic droplets that quickly evaporate, saturating the air with water vapor. Pressing your cheeks builds a little pressure and raises the temperature even more. Finally, release the air in a quick puff. As it rushes out, it expands and cools rapidly, causing the vapor to condense into a visible mist. Just like that, you have created a mini cloud with your face.
