I made this at an art place at my camp. For the tree I used a dot of paint and blew it with a straw and used cotton balls to make clouds. For the red one I used salt. For the green one I dropped rubbing alcohol on it. I shading on the black one and I messed up on the rainbow lol. For the last one I used connect four pieces to make those circles. I think I like that tree the best though :)
