Most Bottles
Could be a pure aesthetic pleasure, used in language work and be a source of wonder - what is it that happens when we turn the bottle upside / down.
Fill with water, a little glycerin, a little food coloring, glitter and small cute / interesting / fun things that can excite children's curiosity. Great when light falls through the contents. Easy to handle for kids, once they turn the bottles up / down, something happens almost magical!
