Make Your Own Ferrofluid in 5 Minutes

Step 3: Mix It! Pour some oil into a mixing cup. Add a bit of the ink, and stir it into the oil. You're making a suspension, so the ink won't dissolve in the oil. Just stir it. Keep on adding ink and stirring until you have a thick solution. There's no exact science to this. A good guideline for identifying a well-mixed fluid is that if you tip ...

Nondestructive Evaluation Techniques : Penetrant

Liquid penetrant inspection is a method that is used to reveal surface breaking flaws by bleedout of a colored or fluorescent dye from the flaw. The technique is based on the ability of a liquid to be drawn into a "clean" surface breaking flaw by capillary action. After a period of time called the "dwell," excess surface penetrant is removed ...
