last weekend boo was So excited about this "science experiment" with daddy. they made a "volcano" out of flour/salt/water, put an empty yogurt smoothie bottle in the middle with baking soda + a few drops of dish detergent + food coloring, and then poured in the vinegar. he wasn't sure what would happen the first time and refused to stand any closer than 10 feet away. after discovering there was no kaboom like the real thing, he mixed a bunch of different colors for the lava himself. overall, a great way to blow off a little steam. :)
