Double Dip Chip – Cool Science Experiment
While some people think it’s no big deal, double dipping your potato chip is the same as putting your whole mouth into the bowl of dip. That’s the hypothesis… but is this true? Leave it to Steve Spangler and some clever fifth graders armed with Petri dishes, chips, dip and an aversion to double-dipping your chip to uncover the truth.

@Stevespanglerscience the Mythbusters were right because they only tested their petry dishes for 1 day. its quite pointless to say that is is better to not double dip, it doesnt make that much difference: the salsa and chips themselves provide so many bacteria, that the double dipping contamination is so minuscule.
Look at the full Mythbusters episode on this if you are not convinced.
You guys are jerks to steve >:C trying to prove him wrong you jerk faces.
@C3Z4rtv of course it is, because that bacteria would be in your mouth anyway
I don't really understand this one…
1:34 to 1:37 thats what she said ;p
you didn't autoclave/sterilize the nutrient agar plates. Those colonies may not necessarily be from the dip but from contamination.
when you opened the Petri dish you risked life of everyone in that room
@mhribi1 lol
@ScarFace9797 you know I am biologist and I can tell you that there are billions of bacteria in every one of those Petri dish. If that bacteria get in your mouth you can get some really bad illnesses. That thing can really be dangerous.
@Stevespanglerscience haha i love your responses to comments 🙂
@KewneRain Nope! =D
i did an experiment kinda like this where i went around my school and took a sterilized qtip and swabbed something. the agar looked like polka dots i swabbed the sink handles
@SuperMarioFan007 broo, they had completely sterile things, chips, petri dishes, swabs and the whole lab… look at this dude…
These shows are so addictive!!!
I am a molecular biologist and i can tell you that the whole experiment that is performed in the video is flawed. First of all you need to sanitize the media. Then you need to be doing this in a aseptic environment. You must have a blank and a positive. And to my eye that does not look like bacteria at all. It is more of a mold! Bacteria would be clumped together and less turbid. I would love to see this redone in the right conditions. And the common bacteria does not take 3 days to grow.
