(B)
When Liam Pope - Lau fell into the ocean during a sailing (帆船运动) lesson,he had no idea what to do. "It really scared me," said Liam. Luckily,he was wearing a life jacket (救生衣) then,but the water was really freezing. "The sudden change in the temperature panicked me so much that I wasn't able to think," Liam added.
Liam's scary experience made him decide to team up with his friend,Fraser Tuck,in his Grade 6 science class at the time. Together they came up with the idea of LifeHeat—a self - heating (自加热的) life jacket that could one day help someone in a similar situation in the water.
After trying many times,Liam and Fraser found that they could use calcium chloride (氯化钙) in their invention. It can create heat and melt (融化) snow and ice on the road in winter. Liam and Fraser put the chemical into a small bag and fixed the bag into a life jacket. When the life jacket got into the water,it could heat the body.
Liam and Fraser spent a lot of time on LifeHeat. They even tested their invention by jumping into the ocean themselves. Now the boys have been working together on their invention for more than two years. They took their invention to some science competitions and won many prizes. They also got some advice from experts.
Liam and Fraser are still working to improve LifeHeat. They hope to turn their invention into a business. "We hope our LifeHeat can help more people who work or travel on the sea," said Fraser.
For kids who want to create their own new technology,Liam and Fraser have advice. "Don't be afraid to try it out because you never know where it could end up," they said.
