March 2, 2024 Page 29 ————————————————————————KID———————————————— Secret of the best stone Do you love skipping stones(打水漂) across the water? Then, you should know the best skipping stone is flat, thin and small enough to hold in one hand. But now scientists say a heavier one, but no heavier than a tennis ball, is also good. That's because. . . When a heavier stone hits the water, a bigger part of it goes under the water so it gets a stronger push from the water. *Top tips: 1 Find the right stone. 2 Flat, calm water is best, like a lake or pool. 3 Turn the stone around quickly when you throw it. Don't throw hard. Instead, try to throw the stone quickly. 4 The best angle(角度) to skip the stone is 20 degrees. *The best way to hold a stone: Hold the stone between your thumb and middle finger. Put your pointer finger around the edge(边缘) of the stone. *The biggest number of skips of a stone on the water is 88. |
