Frustration is tough to deal with. When driven to the point of tears it’s sometimes a short step to lashing out irrationally. Focus in these situations helps, channeling your frustration into something useful. [Yi-Fei Chen] has done that — quite literally — by designing a gun that fires her shed tears.
The gun’s design manifested following a strenuous midterm presentation. Her insistent tutor drove her to tears as frustration clashed with the deep cultural values of her native Taiwan which prevented her from speaking up against authority.
A silicone cup resting against her cheek collects the tears which flow into a chamber of the gun to be frozen. Removing the safety slide preps the round to be fired by the pressure plate trigger on the gun’s rear. It’s simple and it works — tutors beware.
If you’d like to add insult to your injured enemies, this motion-sensing water gun tweets a photo of the victim.

It was calibrated for Taiwanese tears, but does it work with Syrian tears ?
Tears know no race, color, religion, gender, and it´s going to be a very much available material…
Haha, awesome. Ten years ago this would have had unlimited ammo by me.
I’m still, and possibly forever, single.
Yay……..
Nothing wrong with that. Microcontrollers love me in a way no woman could.
But do you love them also?
Or just using them for your satisfaction?
Just remember to use some anti-static protection when enjoying a night with them…

Wrist strap is okay, right?
rutigrem just won the internet by giving this thing unlimited ammo…
everyone knows orphan tears are the most powerfull
Drôle et bizarre
Certainement alors
As much as I like the more rote or technical posts here, I also totally love these oddities and artistic things, too.
At what temperature do human tears freeze?
This is a more complicated question than it seems.
The content Human tears vary depending on why they are produced (lubrication or basal tears versus emotional / psychic tears). Generally speaking, they have a similar salt content and Osmolality to human plasma, but include a vast array of proteins, enzymes, antibodies and lipids.
But in short, at sea level around -0.5 degrees C.
This is a myth. The exact composition of tears will change based on your body chemistry, just like any other fluid, but the notion that different emotions/situations cause different tears is just Facebook clickbait.
You really think an acute increase in the rate of tear production isn’t going to change the chemistry of the tissues generating those tears?
Emotional tears have a different chemical makeup than basal or reflexive (irritant-clearing) tears. They’re still 99% dilute saline, of course, so their physical properties aren’t notably different, but they are chemically distinguishable.
@ Steven Gann; Note I said the difference between basal tears and emotional tears – not different emotions.

This makes me think of the Point of View Gun from Hitchhiker’s Guide
Is the whole world plus the majority of the US ready to cry into a big hypothetical version of this and aim it at Don-Jon and the elephant’s rear? If a cat flap door can be an inspiration for an anti-nuclear doomsday bomb, this is also some idea to use now.
Uh… What?
Please ignore the snowflake above.
My kids make fun of me. I will even cry watching a cartoon.
Thats OK men can cry.

Supacool!!!
Triggers an old memory, Quote:
“Look, water is leaking from their eyes.”
“It’s what they call tears. It is a sign of their weakness”.
Beautiful, nice share hackaday.
The angels sighed, a little girl cried, the tears run rings around my eyes
So sad to think, but what is to be gained?
Taiwan > Education > Tears > Smart
USA > Education > Snowflake > Stupid
