We went to 宜蘭 and this was one of the activities that the driver had planned for us. We went to the Crayon factory (there’s only two there and this is the one that most people with kids go to since the other one is for “better quality” art supplies).
It’s a very streamlined DIY place where you do four things and you rotate through the four things within about an hour or so. You first paint and make a pinwheel, then you make a marker, then you use a pressure machine and make some crayons in castle shapes and then you do some painting on your skin or body part of choice.
Here’s a video of them making crayons with pressure:
