The frightening day of our diving test was here. Our parents thought we were lucky to have an Olympic-size swimming pool at the school. My mom stressed that the swimming pool was one of the best in our city. But I didn’t feel happy about it at all. Instead, I felt afraid of the swimming pool. It was mainly because I was terribly shy.
I was so shy that I always sat at the back of the room in class so I’d not be called upon to read. As for the present physical education class each Monday morning, I would work my way to the back of the line forming at the diving board so I would not have to practice the dives.
Now, it was another Monday morning - the morning of our diving test. My blood ran cold when the teacher Ms. Robbins announced that we would be graded for our final on the most difficult dive- the jackknife. And she added, “This diving test is important. The one who fails has to spare time in the following Monday mornings to practice diving in this swimming pool and attend this test again.”
My body kept shaking with fear as the line to the scary diving board shortened. As I watched, each student seemed to perform the challenging dive effortlessly. And shortly I would have to attempt something that I had never even practiced before.
Then I remembered someone telling me that when you picture yourself doing a skill over and over, it’s just as effective as physically practicing that skill. So I watched carefully as each classmate jumped at the end of the board once, added a jump for height, folded their body in half to reach for their toes, and finally straightened out like an arrow for going into the water. After carefully watching for a while, I was actually in a state of surprise, because all of a sudden I realized that it was possible for me to perform these four steps of diving.
Eventually all classmates except me finished jumping. The teacher announced that it was my turn.

With my heart knocking wildly, I walked down the diving board towards its end.

Jelly ice cubes are made of hydrogels(水凝胶). They can be used again and again, which can save water. Plus, unlike plastic freezer packs, at the end of their useful life, they won’t leave behind long-lived plastic waste. You can also use these cubes to boost garden growth.
Finally, they may make storage of frozen food cleaner. Actually, that’s where “the original idea started,” says Luxin Wang, a microbiologist at the University of California (UC), Davis. As regular ice melts, bacteria can hitch a ride in that water to other foods stored in the same place.
The UC Davis team packed food samples into foam-insulated containers and chilled the food with jelly ice cubes or regular ice. Sensors measured changes in the food’s temperature. Normal ice worked better, but not by much. For example, after 50 minutes, the temperature of an ice-cooled sample was 3.4℃. The sample cooled by jelly ice cubes was 4.4℃.
They also tested the hydrogel’s strength. Its structure is made mostly of a protein called gelatin(明胶). Hydrogels with a higher gelatin percentage were stronger but showed lower cooling efficiency. Tests revealed that hydrogels with 10% gelatin showed the best balance of cooling and strength.
Now jelly ice cubes aren’t yet ready. “This is a prototype,” Wang says. “As we move forward, there will be additional improvements.” The eco-friendly potential of the cubes is the “big goal”, according to Wang. The hydrogel could promote a “circular economy,” she says. “When you use up something, such as these cubes, they could go back to the environment.”
