Introduction: Surrealist Human Hand Stick Shifter!

Picture of Surrealist Human Hand Stick Shifter!

Here's how to cast your hand, and totally rock out your car's stick-shifter!

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

Alginate is a casting powder made from ground up, dried kelp-like algae.
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.

Step 2: Plunge Your Hand Deep Into the Monster's Gullet

Here's where you stick the body part you want a copy of, into the alginate mixture while it's still runny.

Use a container that's big enough!

This container wasn't quite small enough to get the mixed alginate to coat my wrists like I wanted, so I jammed two empty cups into one end of it. Can't a girl get some displacement around here?

Step 3: Wait

play jeopardy or something. invite over entertaining friends.
play one-handed uno with them. fold one-handed origami.

one-handedly solve rubik's cubes.

you can only kill time with one- or no-handed activities.

Step 4: Extract the Limb

It was a little bit difficult to pull out my hand, because there was strong suction from a vacuum behind the alginate.

The alginate jelly-mold was fully hardened, but still able to flex enough to let my hand free with some vigorous wriggling.

Step 5: Mix and Pour Silicone

This is the easy part!

I used some of instructables' leftover silicone casting "OOMOO." Followed the directions on the back, mixed the two parts in a cup.

Once it looked uniformly swirly colored, I just poured it in!

Sink a golf ball on a string, or similarly sized object into the silicone wrist, to leave a space for the stick shifter head.

Step 6: Fahgeddaboudit

Go do something else while the silicone sets.

Like, listen to the Ditty Bops and ride around on your motorized rollerskates!

I don't know how long this takes. Probably the box says.

Step 7: Break the Mold

Picture of Break the Mold

When you come back, your silicone part should be hardened rubber! Poke it a bit to make sure it's not still runny on the inside (like a hardboiled egg).

If it feels done, pull it out!

Feel free to rip apart the alginate. That thing was never gonna last for long anyway. Alginate melts after you leave it out for some amount of time.

Cut some slices in the base of the wrist, and extract the golf ball. You may have to pull pretty hard.

The golf ball and the slices make the perfect-sized and -shaped hole for the hand to slip over a stick-shifter knob.

Step 8: Bask in Surreality

One of the better parts of putting the hand on a dash-shift car is that the hand appears to float just above the dashboard, in a very creepy, human way. Passers-by gawked quite a bit.

Fortunately, especially given the skin-tone hue of the oomoo, it's apparent that the hand isn't connected to anything like a human body.

Also, after you make this, you can walk around wielding the hand and asking,
"Hey - can I lend you a hand?"

Ha! Creepy and totally awesome.

goosenoose (author)2011-06-04

Fantastic idea! I am definitely going to make one of these for my first car that I'll be looking for tomorrow.


ps. do you know if OOMOO comes in any other colors/skin tones? Like yours perhaps; I'm a bit more sunburnt with all the running I do down here in southwest NM.

What happens when you get pulled over?

dla888 (author)DAND2010-01-13

Explain to the cop that it is only a silicone model and that you are NOT a deranged serial killer.

biggunner (author)dla8882011-01-13

but that would be a lie... hehehehehe.
i use real hands....

chicopluma (author)biggunner2011-04-10

it's ok, you can also go to jail, i mean, it's an option

dla888 (author)biggunner2011-01-15


djr6789 (author)DAND2010-10-05

back hand the cop with the stick shifter

Giesterfarher (author)2011-03-11

I'm going to get my GF to let me make a cast of her lower leg and foot so I can use this in my F100.


m5industriesinc (author)2010-10-03

where did you buy the alginate and how much?

Fado Korok (author)2008-08-29

What is the consistency of the finished product? Is it rock hard, or is it more jelly-like?

yes that is what i would like to know because I just bought a stick and I am wanting to do this. oh and i want to cut a sleeve and attach it to the hand. it would have some blood, maybe some missing fingers and stuff. ahhhh I love zombies... what was I saying? oh ya the consistency of the hand? .

michael lively (author)2009-05-06

I too rock the curly hair.

Airsoft_ninja (author)2009-04-02

Very "Handy" LOL nice job

stasterisk (author)2008-08-20

Are those copies of your fist?

bustedit (author)stasterisk2008-08-20

eh, no. those are, shall we say, "marital aids".

abadfart (author)bustedit2009-03-21

its ok I'd put sex toys on my gear shift... my GF would get a kick out of it

Nabil (author)stasterisk2008-08-20

those are adult toys...

darkmuskrat (author)Nabil2008-08-20

yah, should blur those :P

bustedit (author)darkmuskrat2008-08-20

i'll remove them, but if no-one knows what they are, they shouldn't offend.

Nabil (author)bustedit2008-08-20

Sorry if I caused trouble! Wasn't my intention, I just wanted to answer to stasterisk. In fact in the adult entertainment industry are great materials and ideas to other uses.

bustedit (author)Nabil2008-08-20

no trouble. i deleted the comment, but i think it was removed by higher-ups as well. i do not want to offend anyone or make them uncomfortable...just the idea of a rubber fist and it's intended purpose blew me away the 1st time i saw it!

Nabil (author)darkmuskrat2008-08-20

a hand is a hand... the issue is the use...

bustedit (author)Nabil2008-08-20

xactly, and not mine. just a pic i found for the purpose of illustrating my idea of bought vs. homemade.

cheeto4493 (author)2008-08-22

Cool, I think I might try it in an arm wrestling shape though. I'm always wrestling with my car to get it in the right gear. It never wants to slide into reverse. BTW where'd you get the cool wind turbine shirt.

abadfart (author)cheeto44932009-03-21

ya i have to hold mine in 2nd

stasterisk (author)cheeto44932008-08-23

I love it! Post photos!

The shirt is from Massachusetts Power Shift:

hackerlife (author)cheeto44932008-08-22

uh, to get it into reverse i think you need to pop it into first (or any gear) because the the synchronizers line up the gears. i'm a new driver with a stick shift car, so i might not be trustoworthy.

abadfart (author)2009-03-21

you have the same truck as my friend dose your 5th stay in or dose it pop out under sixty?

abadfart (author)abadfart2009-03-21

also wouldn't a fist work better

exipom (author)2009-01-26

i ffel so ronery... i need one of these. so funny xD

remmelt (author)2008-08-22

This is superb. But why stop at a gear stick? - bicycle handles - door knob - mouse (make a fist, install mouse hardware inside) - coffee cup handle - those little handles under office chairs The possibilities are endless.

stasterisk (author)remmelt2008-12-16

Hey, looks like Tim got to the human-interface silicone Mouse idea, but with a bit of a twist...

stasterisk (author)remmelt2008-08-23

Sounds good! Send photos!

bowchickabowwow (author)2008-10-02

this is awesome

RainbowZen999 (author)2008-08-27

This is just hilarious. I wanted to know how to make a mold of my hand anyway, but it's really funny using to put on your stick shift.

beauwalker23 (author)2008-08-24

this is disterbing yet amazing. i would proble freak out when i touched it and didnt expext it. haha

neardood (author)2008-08-22

Lol when you change gears you give him a high-5

Bisquick the ninja (author)2008-08-20

You could just kill a wannabe ninja and take his hand,Stick it in some formaldehyde,remove some bones and slip it right on!

Yeah, and the perfect wannabe ninja is you, you can't-describe-ninja-weapons'-name-properly ninja wannabe. Nah JK. Oh, and if you're thinking of replying to this comment, use the reply button so I would actually know you replied to my comment.

Derin (author)2008-08-22

joystick type shift sticks rock! the old rod type is uncomfortable

Derin (author)Derin2008-08-22

also,why did you put this into the dash?

teddywookie (author)2008-08-22

Hey! You're still out scaring the straights! As a straight, I appreciate this.

Snerdguy (author)2008-08-22

That is really neat. Now all I need is to cast the rest of a person for a passenger so that I could use the car pool lane.

rattyrain (author)2008-08-21

Veddy niiiiiiiiiiiiice!!!!!

Notags (author)2008-08-21

Jalopnik.comYour "helping hand" has made it to

andyhuntdesigns (author)Notags2008-08-21

That's awesome! Congrats Stasterisk!

tbenefi33 (author)2008-08-21

Hay think I'll make a big foot and say I found big foot they can't fire me cause I'm not a cop...LOL

Kaiven (author)tbenefi332008-08-21

LOL i remember that...

old_bass_masta (author)2008-08-21

Paint with fake blood anyone? that would be verry creepy to see. you should have like a severed arm with 2 plaster bones sticking out. would look good
