Trivia questions

I'm doing a trivia game for the kids tonight at our indoor-because-it's-raining Lag B'Omer party at the shul.

I really ought to write some questions for it.

So therefore, I turn to you, my friends -- any good suggestions for trivia questions, on any subject, suitable for an audience ranging in age from, oh, five or so to, oh, maybe thirteen or so?

One possible solution to the dizziness in the house thing

Plants. Plants filter and clean the air. And someone's published lists of houseplants that are particularly good at filtering out formaldehyde, benzine, and trichloroethylene, which are, apparently, the indoor pollutants most common, and most likely to cause the things which have been making me wobbly.

There are also lists of plants which are toxic to cats.

I cross-referenced them.

Here is the complete list of plants which filter out toxins and are not themselves toxic to cats:
-Spider plant
-Bamboo Palm
-Gerbera Daisy

I begin to wonder if the reason that many of the plants which are toxic to cats ARE toxic to cats is that they encapsulate and hold large amounts of formaldehyde, benzine, or trichloroethylene.

Fortunately, spider plants are really easy to care for, and bamboo palms are nice-looking, but gerbera daisies don't do much for me, are somewhat trickier to care for than I was hoping for, and are the more important ones since they deal with benzine and trichloroethylene, while spider plants and bamboo palms are mainly good for formaldehyde.

So, when we get back into the house, it's off to the greenhouse for us, I suppose. See if that helps things.
