we've looked at fish, now chips

Last time you were sitting at your favourite black jack table did you wonder where all those chips and money were disappearing after being swept up by the dealer's little broom? The answer should be obvious by now!

Several pneumatic tube companies have specialised products for their casino clients, such as Lamson's automated system (described as the "evolution of the drop box", putting a whole new spin on that place we all store our files). Aerocom has systems for gaming pits, count rooms, cash cages and high-roller rooms (amazing words, most of which I didn't even know existed before researching this post).

Pneumatic tubes aren't only in modern day casinos, but have appeared in famous casinos from the past, such as the Resi in Berlin. You can read more about the Resi on one of my previous blogposts, as well as here, at Caberet Berlin.

So we've looked at fish, and now chips. For those interested in both, you can read the fascinating history of fish and chips here!

flying fish

You've probably heard of fish ladders, but have you heard of fish pneumatic tubes? This is one of my favourite recent pneumatic tube discoveries - the use of the system in fisheries to move fish around. I reported on it a few months ago in my ten bizarre and incredible uses of pneumatic tubes list. Now the system is making more headlines.

Labelled the salmon cannon, the digital magazine Takepart discusses the use of the technology to separate wild and farmed fish, a task normally done by hand. It's seen as a much more fish-friendly option, the salmon reportedly departing from their pneumatic voyage unscathed. Not all commentators on the story were convinced. Environmental organisations though seem to be on board.

"It may be funny, and it may sound ridiculous, but we're dealing with the serious issue of fish and water usage" Whooshh's vice president Todd Deligan told the magazine. A historian at the recent infrastructure conference I went to in Copenhagen asked me; how do the companies deal with the serious issue of selling something seen as so fun? Obviously from Todd Deligan's comments, it takes a bit of work to convince the public there is a serious side to flying fish through a tube.
