This is sort of in the spirit of donnauwanna's silicone breast squishy toy, in that I thought it would be awesome if people could hold my hand even while I was far away.
I wanted to learn all about silicone casting and molding in a hurry so I could make prototypes for Fuzzy Logic
I think few people who drive manual transmission cars actively think about driving as controlling a gigantic machine moving with a lot of momentum, via a huge rod that goes directly through the floor and moves a set of meshing teeth around in an engine that's actually running. It's one of the few places today where you're moving mechanical bits around in a real machine. So the idea behind the hand is to remember that you're working with the car to make it move, sort of holding the car's hand.
Turns out this hand is super-versatile, and fits on almost any shifter knob!
And I thought it'd be hella funny to see a hand reaching up out of the floor of Tim's beatup diesel pickup truck.
I think the installation plan is to attach some kind of sleeve to complete the look, but I'm not in charge of that. Hopefully there will be pictures.
Step 1: Mix & Pour
It sets at body friendly temperatures, and conveniently sets faster, the hotter the water you use.
This makes it very easy to control the mold-setting time.
Measure the amount of alginate you want, and mix it with an equal amount of water by volume.
Do a better job than I did.
Mine looks like chunky vomit because I added alginate powder to water, and tried to mix it slowly with a spoon.
The alginate contacts water and makes a gel that encapsulates big powder bombs that never quite mix into solution. Avoid chunks. The smoother and more like paste, the better.
Get better results by (instead of adding alginate to water, like I did) slowly adding water to alginate powder. Mix vigorously, maybe with something like a fork.
The alginate starts to set surprisingly quickly, so do this part briskly.
