I have a hydration pack that sat in storage over winter. I pulled it out last weekend, and I found that the tube from bladder to bite valve has a thin white coating inside it. I tried rinsing them out first with a mild bleach solution, then a vinegar one. Neither of these removed the stuff from the tube. If I squish the tube, the coating comes away from the tube. How can I remove this gunk from the tube? Would I be better off buying new tubes instead of cleaning?

I have a 36 inch diameter round window in my shower. I would like to find a 36" outer diameter tube in some material (pvc? wood?) to line this window. It will be painted. I'd want a piece about 6 1/2" deep so I can trim it down to fit with a slight lip. Looking for ideas for sourcing this, as I don't need feet and feet of it, and would like to keep costs down. Help!

Hi there I am trying to find an advert from around 2009 that, as I remember it was... 1) For a mobile phone network (although not a major one); 2) Depicted a purple cartoon-like character holding a spray can or a marker; and 3) Had a "graffiti" style typeface or logo. This advert ran on the London Underground, however, due to LU's advertising policy, it was the logo and character were edited so they bore no reference to graffiti. Please help!

i want to document in order, the merits of different methods of estimating performance for copper tube aluminium fin heat exchangers. ashrae standard documents the most valid methods of testing, basically with a primary method and 5 confirming methods. to do a paper study, there are many ways to go about it. what i want to do is review and collate these methods, as a background to the development testing my company does. however i don't want to do the legwork if there is already an analysis that covers the general structure and merits of the theoretical methods. is there anything out there that does the comparison for me?
I have escalophobia (vertigo related) and so as a rule avoid the extra long escalators on the tube network (namely Angel, Holborn and Leicester Square) as I've previously had panic and vertigo attacks on them. This evening I need to get to Goodge Street and TfL recommends I change from the Piccadilly line to the Northern line at Leicester Square. I'm struggling to find out from google whether this change involves using the very long escalators. Do you know? [more inside]

I've got some cardboard tubes from plastic sheeting - in all different lengths and widths. I want to be able to put shelving on them - so I'll be needing a round disk that'll fit in about 1/2 an inch snugly and have a screw protruding so I can then bolt the wood to the screw and tube. What is this disk called and where can I get them online?

Very active one year old with G button (MIC-key low profile) During night feeds and traveling in car how do I keep her Button from being pulled?
