When it comes to smoke absorption, there are a few different things that can help. One of the most common is to open up all the windows and doors in the room to allow for ventilation. This will help to dissipate the smoke and clear the air somewhat. Another option is to place a wet towel over the opening of the door or window to help filter out some of the smoke. Some people also like to use fans to help circulate the air and remove some of the smoke from the room.
In terms of materials that can absorb smoke, activated charcoal is often used. This is because charcoal has a large surface area which allows it to adsorb (or bind) with various molecules, including those found in smoke. This can help to reduce both the smell and amount of smoke in a room. Other materials that can be used for this purpose include baking soda, coffee grounds, and even cat litter!
