@devonscience: Urghh, don't use a hand dryer😱🦠 ----- Update: thank you for all your comments & suggestions. Totally blown away by how far this little video has reached 😮 I'm planning on doing some update videos on this experiment and will post on here, as well as on our FB & IG pages, which you are welcome to follow as well 😉 Thank you, Ruth (from Devon Science) #germs #publictoilet #bacteria #dirty #gross #justdont #scienceteacher #handwashchallenge #handdryer #Science #scienceexperiments #microbiology #scienceproject #lesson #handdryer #handdryerbacteria

starlightthedark :

I genuinely wipe my hands on my shirt because I don't like the noise of a hand dryer

Aisling MacCraith Ó :

Why’s it so dirty?

Gordon λ :

Should of done the air one in the bathroom too

selina :

okay but i NEED to know if drying your hands on a paper towel/toilet paper that‘s been hanging in the bathroom air is any better please

lydiaroots :

I feel validation. thank you

️ :

guys there is already lots of bacteria in the toilet air, the reason the wafted one has less bacteria is becouse she didn't do it in the toilet, use a hand dryer if u want. 👍

Khaleesi & Violet :

I dont use it either

thal.carat :

I will never ever use one again.

Tboz •Group7😆 :

Sheldon told us this a long time ago😩

Oi bruv :

You cannot draw the conclusion that paper towels are better if you do not also grow bacteria from a swab of the paper towels.

martintighe189 :

not a fair test. you should have wafted the control plate in the restroom air, not the workspace are.

Mandy 🏴󠁧󠁢󠁳󠁣󠁴󠁿 :

Doesn’t the soap u just washed your hands with protect you from hand dryer bacteria?

Michelle :

What on earth. There is no contact with the hand dryers. Where are those germs coming from ? Also I would have thought the heat would kill off bugs. I am not longer a hand dryer user.

bethanhannahxx :

1- I just want to say there is absolutely no way that nothing would grow on an agar plate you wafted in the air. One of the main parts of the streak plate technique is to place your agar plate under

JessicaGray :

Learned not to use hand dryers from Sheldon Cooper. 😂

btcompksu 🌻 :

What about one of those blade air "hygienic" dryers?

kingkiell Nickiell :

hmm what about the tissue? and the bathroom air itself (as others have stated). I'm curious to see. oh and the water too.

💕Laura_D💕 :

what scares me is I work for the NHS and they took away our hand towels and we are forced to use the hand dryers..even removed the bins so couldn't use the loo roll to dry!

DudeSwitchingMJ2WG🇺🇦 :

could you do this with a dyson air blade. I was an apprentice designer when they were working on this for this exact reason

Chris Ross :

should have wafted the tray in the bathroom as well. peer review not an overt criticism😅

Pickers4 :

But you've just washed your hands so the bacteria won't live on your hands anyway

Sam :

the better test would be to test your hands before, after using a hand dryer and after using the tissues. I'll bet there's minimal differences.

Wish I'd Known That Before :

thankfully my hands are neither made of, nor covered in agar
