I don’t know if it’s still there, but when I visited the town of Ayr in Scotland about 25-ish years ago, they had a playground very similar to that right off of the beach. Everything was large enough to accommodate adults, and I think it may have actually been castle themed. No ball pit though. They did have a thing like a tilted merry-go-round that was at waist height and had no handles. Not sure what it’s called, but it was probably the funnest and most dangerous single piece of playground equipment I think I’ve ever come across. There were about a dozen of us traveling together, and I don’t think a single one of us walked away from that thing without catching a boot to the face at least once.

Weed whackers and weed eaters were used fairly interchangeably where I grew up in the US southwest and mountain west.

If the process and tradition of it appeals to you, then sure. You can find a cheap matcha set for under $20 (I think I saw one on Amazon a while ago for $10), so it’s not like you need to spend a ton of money to try it out.

I’m kind of lazy so I use one of those electric milk frothing whisks instead of a traditional bamboo one. But if you use that type of electric frother just be sure to use it in a vessel with high sides and a fair amount of extra room otherwise you’ll be wearing your matcha instead of drinking it.
