Clouds are made up of water vapor with the amount depending on temperature and pressure. Dropping temperatures mean not as much vapor. Water condenses on the dust floating in the air so the amount of droplets in a cloud depends on how much dust and water vapor there is in the air, as well as the temperature. People and objects can move through clouds. The water droplets are really too small to touch so it is similar to the feeling of being outside on a really humid day. Clothes might feel moist and the air feels thick and heavy.

Can you touch a cloud?
Clouds are the condensed form of atmospheric moisture consisting of small water droplets or tiny air crystals. The formation of clouds caused by the cooling of the air results in the condensation of invisible water vapor that produces cloud droplets or ice particles. The cloud particles are minute in size so they can be sustained in the air but not felt.

Can you touch a cloud?
Many clouds appear solid because they have such definite shapes. but they are nothing more than parcels of tiny water droplets and ice crystals floating in the air. The different shapes of clouds are a result of the way they form and the balance of water droplets and ice crystals within them. The water droplets are so small they cannot be touched.
