    a hydrophobic knife might just give a tough competition to the deadly icicle. A video uploaded on TheXvid by a channel named ‘Action Lab Shorts’ shows the difference between an ordinary knife and a hydrophobic one. The video starts with a beaker full of blood (Not human blood, of course!). The presenter then dips the ordinary knife in the beaker, and it turns all red when he takes the knife out. Howbeit, when he dips the hydrophobic knife, it comes as clean as it was before.
    To take it up a notch, the presenter tries his own blood in the next part of the video. He pricks his finger and gets a speck of his blood on a microscope slide. He then touched the hydrophobic knife on the slide, and the results are the same.
    Well, it might have been the perfect weapon for a serial killer before the presenter puts the knife under a microscope. What is seen are big blots of red blood on the blade when seen through the lens. The presenter exclaims, “Look at that! Busted!" The debate is washed off, and apparently, the icicle still remains the perfect murder weapon there is.

    The perfect murder weapon for me is insulin. My sister is diabetic, so i've already git a source of it, you don't need to much, it leaves no trace, and it is technically natural considering we all produce insulin. The only thing that I would watch out for is cold insulin, my sister says it hurts more and I think she's mentioned it leaving a bruise before.
