How to entertain children

How to entertain children?I have very developed children and they are constantly demanding something new in their development. I'm tired of wondering what to think of. what are your options, what do you do for your children?

You're right, there are plenty of activities for children, but nothing will surprise them nowadays. We go to different clubs and extra activities. But for home, we recently bought discs for homestar planetarium https://astronomix.info/planetarium-discs.html It's an incredible experience. We turn it on at bedtime. The child is very happy. He starts and ends the day with this planetarium.
