Pick a company you enjoy.
A biker buddy of mine was gifted a few shares of Harley Davidson stock and it was a fun thing for him to own. If you like Disney, there's that; or you could go for your favorite cruiseline, beverage, running shoe, etc.
I'm not saying this in any derogatory sense, but you are gambling. So do it in such a way that is most fun for you, rather than ask others for "hot tips" which are no more than letting some stranger pick your roulette numbers. Think about the products you buy and businesses you enjoy patronizing and go with that as a starting point. It's fun to invest in companies you know. In college we had to do these projects on companies like RJ Reynolds, Hershey, Heinz, McDonald's, Phillip Morris, etc and make business recommendations for them. One of my classmates' presentation was on L'Oréal. It was decades ago, and we knew very little, but it was interesting to see what was behind the brands, what kind of debt a company had and do our own speculation about how they might merge, grow, modernize, compete, etc.. I did eventually go into an equities IT job, but not equity research directly.
With my invest-for-fun money, I buy art. It's an investment, but there is enjoyment in the tangible object, too. The keys for me include not buying collectibles (which are not art) and not simply getting anything someone else thinks is "hot" because I'm the one looking at this thing. It's going to be on my wall. It has to speak to me. This was what kept me from getting into a Thomas Kincaid trap. I've got a few sculptures from local artists, a couple of water colors & sketches also from local artists, and a couple of oil paintings and water colors from other countries. Some have come direct from the artists themselves, some via galleries, some via auction. This is under a dozen pieces over 20+ years. The art itself is enjoyable to own, but the process of learning about the art is also fun. Gallery openings are free entertainment. Alas, I don't drink, but it used to be a way to get free wine. Still a free way to spend date night.
Some of the art has gone up, some might have little or no resale value, but I don't need to sell because it'll hang on my wall until I'm dead. It's still got value for me. If I had $100 and not enough art, I'd head to a number of local art shows and estate sales and see what was available. Or I'd buy silver flatware to use and sent my crappy stainless stuff to the Goodwill.
Have fun.
