New Product Idea and Book Giveaway -- Who Wants it? (N95 straw)

[Stephenk53]

A barrier of some sort?
Think and brainstorm some more of what type of barrier could do this. ie Create another flow of air from your flow.

( No one said "No coaching!" )

Perhaps it has a fully closed end but has a mini fan that when you blow on creates a tiny electric charge that then activates a relay that allows a battery to power a larger fan to blow out the candle

Last couple days to submit your product ideas. There have some very good ideas so far, both from professionals and hobbyist folks.

BTW, I bought a copy of the book that is being given away in this contest, and I received it yesterday. Here is what I posted about it in another thread -- fun book!

Enhanced the photos and did some reading already ...

LOL. I guess that's covered under "Fair Use" copyright law...

Because the PF was down for most of yesterday, I'm extending the deadline for submissions through the end of today. The two winners of the book will be announced tomorrow. Thanks for a fun thread, folks.

How about a turbocharger whistle candle blower-outer.
No filter required.

I found something similar online, though I think it's just half of what's needed.

ps. I watched a video with Clifford Johnson, the author of the book, and he has a British accent. So I checked out his wiki page, and found that he was born in London, 50 years ago, today.

Happy Birthday Professor Johnson!

pps. Hope you didn't spit on the cake!

ppps. @berkeman , did you do all of this on purpose? Had the forum shut down for a whole day so the contest would land on his birthday? If not, that's quite a coincidence, methinks.

I may have started reading the book already but my expectations for the contest aren't too high (I'm just amateur/hobbyist). [Of course ... you never know! ... ]
But in any case it seems that everything I have to propose here comes from the combination of two of my previous posts. I present it here again fully, dividing it now into 3 parts:
A)

here's the solution that I propose: filter on the mouth (+ either straw or not) ...
[Simple!]

Edit note: I'm not just saying this as a joke, but the idea comes from surgery [facial] masks etc.. The question is how you get an effective blow and how hard you can blow etc. , but I think that with the right construction of the [mouth] filter / mask it would be possible.
(No need to mention though that I am an amateur/hobbyist in those ...)

B)

other idea: multiple straws, all connected to one filtered end etc.

C) In case we want to use the heat from the candle flames as "germ deflector shield":

How can you focus "the blow directly on the flame"? (Perhaps having many straws, with a variable space configuration, each one pointing on each candle ? ...)

 

[berkeman]

Oh my goodness. The professional entry seems to be a lock, but the amateur entries are so close... Ack!

E-gads. I've been had.
I will have to like that one.

I'll take a shot at it, first to get more air through the filter you need more surface area, so put the flat filter at an angle to inside of the straw, you can make the angle less steep the longer the straw is :-)

 

[Stavros Kiri]

E-gads.

Here is another wild idea!: perhaps create a "Candle Blowing Suit", with all the gadgets attached to it ... . You get in ... you blow the candles (for your birthday) - everyone's thus sanitarily safe! (especially if you're sick with the flu or something) - then you come out of the suit and continue with the party! ...
Now that's an idea for a tech product too!

 

[berkeman]

Okay, contest is closed. Great stuff. The winners will be announced shortly.

Congratulations to our two book winners! @Greg Bernhardt will be contacting each of you to verify your mailing address.

I like all the creative alternative ideas that folks came up with. My initial idea was to widen the straw for a bit to accommodate a section with the N95 filter in it, and then neck it back down to get the air velocity back up again. But I like the variations with angled filter material, and a longer curvy straw with some absorbent material distributed along the inner wall.

The breath-powered air pumps are pretty clever, and fairly practical.

Thanks for a fun thread. Where's the cake?

 

[OmCheeto]

Yippie!

ps. I did finally finish reading the previous book sent out: "What's it like in Space", just yesterday morning.
10/10 stars!

 

[BillTre]

I was thinking of getting this book, so, NICE!

 

[Stavros Kiri]

Congrats to the winners! It was indeed a fun thread, and thanks to the OP too!
When should we expect to get the product running and be able to buy it? (Funding will be needed, as usual ...)

Absolutely. An added dress up phase for the celebrators which would be fun.

congrats winners!
