On December 12, I went to a science club performance yesterday. The most interesting thing was that the submarine boy demonstrated the submarine to our audience. At first, he put the submarine by the lake, and then activated the remote control of the submarine.
The submarine soon sailed on the lake, and soon disappeared into the water. It was floating on the water again. When I got home, I was still in the storm.
I captured me with science. I hope that by joining the science club in this way, I can learn more knowledge to realize my dream: delicate models driven by solar energy.
In April this year, the U.S. Navy's "obanon" found a Japanese submarine patrolling near the Solomon Islands. The American crew shot down the submarine's command tower and prevented it from diving.
However, the submarine soon approached. When the Japanese sailors went ashore to fight, obanon's artillery could not hit the submarine. The unprepared crew of obanon hit them with a hammer - potato thought they were hands Shrapnel, the Japanese panicked, dropped their guns, tried to submerge the submarine, and then they were forgotten.
The new lieutenant was assigned to the submarine, and since a little boy tried to impress the captain with the expertise he had learned at the submarine school, he had dreamed of working there. The captain quickly cut him off and said, "listen, sir, it's very . Add the number of dives we've made to the suce of the water and divide it by two.
If the result doesn't even come out, don't open the hatch.".
