When dry ice melts, it turns into a gas. So when you see dry ice "smoking", it's frozen CO2 melting into its gaseous state. Dry ice is a popular matter in scientific experiments. It creates projects that look cool. Experiment: Healthy dry ice popsicles（棒冰） This dry ice experiment will catch people's eye, especially little kids' because the dry ice is going to be used to make what the young love to eat. It should take you about 10 minutes or less to have a frozen treat to enjoy.

Cyclist Ben Jones said the group settled on a goat because it was an easy animal to draw. He said the ride lasted more than six hours, with the four men stopping only for food, and flat tyres .
