35mm Film + Hydrochloric Acid = This!

We love all sorts of analogue experiments and this one by a Chemistry and Physics teacher from South Carolina is pretty damn cool. Check out the picture he tweeted of 35mm film dropped into hydrochloric acid! Can you guess what happened?

We here at Lomography love all sorts of experimentation on film, especially film soaks! From hot water to baking soda to laundry detergent, Lomographers love to get wet and wild!

So when we saw this tweet by MattAttackPro (a science teacher who possibly works for NASA launching rockets), we just had to share it with you!

“The beauty of chemistry! Soaked a piece of unused film in Hydrochloric acid.”

So what’s the lesson for today? When undeveloped 35mm film is dropped into a beaker of hydrochloric acid, the emulsion separates from its clear plastic backing. Yup, those yellow swirls are the coats and layers of light-sensitive salts suspended in gelatin that make up film’s emulsion (dull) side!

Warning: Don’t try this at home as liquid may be toxic. Also, it’s a waste of good film so keep shooting instead! ;-)

The Lomography Color Negative 35mm 400 film delivers vibrant colours and superb saturation and contrast. You don’t have to worry while you’re shooting, even under low lighting conditions. See our selection of Lomography films here.
