Last week we went to a science class. One of the mom's in my mother's group is an elementary school teacher that specializes in science and she invited all the students to attend a little science class at a local rec center. All the kids were amazed by the experiments conducted. We watched water turn into gas using dry ice, we mixed baking soda with vinegar to create gas bubbles, and we melted ice using salt.
But their favorite experiment by far was blowing up balloons on a bottle. We mixed equal parts of water and oil in a plastic bottle. Then we broke up alka-seltzer tablets into a deflated balloon. Next we put the balloon over the opening of the bottle and let the tablets fall into the water and oil. Slowly gas will form in the bottle and blow up the balloon. The kids thought it was magic. Elizabeth and Jackson liked theirs so much they wanted to take them home. She has some great ideas for household items that we have and could use to create a little science magic on our own.
