Making fog is a fun project to do with your kids. You will need a soda bottle, ice, rubbing alcohol and hot water. Take you 2L bottle and fill it 1/3 of the way with the hot water. Then, add a few drop of the rubbing alcohol. Lastly, put a piece of ice over the top of the soda bottle and watch the fog develop. If you need a large amount of fog then use dry ice when you add it to water it will make fog. Be careful when handling the dry ice as it will burn your skin if you don’t wear gloves.
