"Penny of Time" Adventure: Service Act Meets Science Experiment. My four year old loves his hush bottle. He wanted to make one for his friends . . . in the process of doing that, we ended up making 6 and dabbled in some experimenting all the way. A great activity for an afternoon when the weather is rainy or too hot to play outside. Teach children to serve.
Did you know if you mix milk with Red Bull, the milk will curdle? Pour milk (whole milk works best) into a glass. Then, pour Red Bull on top. Let the solution sit for five minutes. The acid in the Red Bull causes the protein (casein) in the milk to separate. This is a great experiment to do with a states of matter unit. When the milk curdles, a chemical reaction takes place, resulting in a precipitate.
