im doing a science project and i want to know how to get mold or mildew to from on a tile
Make sure that you are not using a sealed/finished tile. A terracotta or the back of a ceramic tile will work as long as you keep it damp. To start soak the tile overnight in a bucket of purified water, not from the tap. Tap water has chemicals to kill off the spores for mold/mildew. You'll need to always keep the tile damp so a warm damp place will be needed. If you know of somewhere with some mold/mildew spores growing, that'll speed things up. Otherwise, it may take weeks to grow naturally. If you do have a source for the spores, use a Q-tip swab to wipe the spores off and onto the tile surface. Good Luck
