It seems foolish to wish fun & silliness when the world is such a mess but wish it we do. Barring blasting out of a cannon (or a cardboard tube), you could do a few things that are a bit more subdued. See a fun list in the MakeUseOf directory. Everything from a llama font to making your own music. (The site is absolutely family-friendly.)
