Step 2 Activating the Aluminum Strip

Add a drop of liquid metal (I got mine on eBay.)
Smear the liquid metal on the shiny aluminum surface.
When the liquid metal "wets" the aluminum surface, the strip is ready.
I sort of stir the liquid metal on top the aluminum, scratching the aluminum beneath.
The aluminum is wetted when the liquid metal sticks to the surface.

The idea is that gallium stops the aluminum from forming an oxide layer.
When aluminum gets in contact with water usually nothing happens because the oxide layer acts as a buffer. When the oxide layer is scrapped off aluminum, a new layer rapidly forms preventing any reaction.

Liquid metal is an alloy of gallium, indium, and tin so it acts as a source of gallium. Liquid metal is non-toxic (but I advice against injecting yourself with liquid metal... just in case that crosses your mind).

i need to know where i can find it liquid metal

[Kryptonite]

Is this "liquid metal" Galinstan?

[backscan]

So John Connor could have just thrown water and aluminum on the robot to kill it?

[SteadyEddie]

thats damn genious lol

[backscan]

There's a fine line between genius and me I think they call it sanity ; )

[pindi]

would be cool to have liquid metal running through ur veins, like X-men! no, that was a joke, dont try it kids!

[Biotele]

It will give you a stroke if it is arterial or the person has an atrial defect. And if injected by vein will result in pulmonary embolism. Seriously dangerous.

That means no right? Should i call 911 now? kidding

[Biotele]

Yes, inject that stuff is bad.

[codongolev]

shiny....

[revelation]

where do you obtain a syringe filed with liquid metal ? I want to see if its a good high !

[budsiskos]

why use liquid metal? you can do the same by smearing chocolate on the can

[Biotele]

by jove, brilliant! You should also try other brown stuff!
