Why is this the answer?

The answer is fountain because this clever riddle is describing an object that is full of lively water. Think about the first line: "I bubble and laugh and spit water in your face." When you see a fountain, especially one with water shooting up high, the water often makes a bubbly noise as it lands back down. That splashing and bubbling sound is what the riddle means by "I bubble and laugh." It sounds very happy! If you are standing near a fountain, especially when the wind blows, tiny drops of water sometimes spray out and hit you. The riddle calls this "spitting water in your face," which is a funny and exaggerated way to talk about the mist or splash that touches you. A fountain also fits the second set of clues, which are there to make you think about something else. The riddle says, "I am no lady, and I don't wear lace." This is a clever trick to make you look for a person or something delicate. A fountain is a heavy, strong structure made of stone or metal, not a person. It is not delicate like a lady, and it definitely does not wear fancy "lace" or clothes. Riddles often give you big, clear hints with the first lines, and then use the second lines to be a little sneaky and throw you off track. This puzzle works because it uses human actions, like laughing and spitting, to describe the sounds and movements of the water in the fountain. The water is constantly moving in a fun, exciting way, and that is why it is the perfect solution to this playful riddle. It is a beautiful object that looks like it is having fun all by itself.
