Once, it suddenly occurred to me why not let two snails race? Do it. I put two snails on the card and marked it carefully.
The game is about to start. I invited two players to play and let them do "warm-up exercises". At the beginning of the game, as a referee, I was anxious like an ant on hot bricks, while these two players were crawling slowly. It took two snails about four minutes to climb five inches. How slow! I have to wait patiently. Finally, the first runner crossed the finish line and won.
I observed it carefully and found that there were two shiny lines where they ran. Interestingly, athletes even draw "runways" for themselves!
In order to treat them, I put a small piece of cucumber and a small piece of tomato in their room. I watched them with interest. I saw that snail 1 only picked cucumbers to eat, and snail # 2 only picked tomatoes to eat. I watched them eat with relish and laugh happily.
After dinner, when I visited them again, I found red and green feces in the "living room". In order to find out, I fed snail 1 a little orange and snail 2 a little melon, so I'll wait and see.
The next morning, when I visited them, I found some yellow and white feces in the "living room". From this, I understand that the color of snail feces is related to the pigment in food.
These two little snails are really interesting! They bring me happiness, knowledge and a studious heart.
