NASA's Sound Suppression Water System
If you’ve ever watched a rocket launch, you’ve probably noticed the billowing clouds around the launch pad during lift-off. What you’re seeing is not actually the rocket’s exhaust but the result of a launch pad and vehicle protection system known in NASA parlance as the Sound Suppression Water System. Exhaust gases from a rocket typically exit at a pressure higher than the ambient atmosphere, which generates shock waves and lots of turbulent mixing between the exhaust and the air. Put differently, launch ignition is incredibly loud, loud enough to cause structural damage to the launchpad and, via reflection, the vehicle and its contents. To mitigate this problem, launch operators use a massive water injection system that pours about 3.5 times as much water as rocket propellant per second. This significantly reduces the noise levels on the launchpad and vehicle and also helps protect the infrastructure from heat damage.

Champagne Mojitos Recipe - John Besh
sounds like a decent party starter:
This puckery drink is prepared with rum and fresh mint like a classic mojito, but New Orleans chef John Besh makes it holiday-worthy by topping it with a splash of Champagne.

How to get your water tested for lead in Dublin
Ossian has written up this very informative post:
Irish Water is writing to thousands of people living in Dublin this week to warn them that their water is supplied through lead pipes. Irish Water says that most people receiving these letters have a level of lead in their water which is above safe limits. So, if you get one of these letters how do you get your water tested? Irish Water is refusing to supply test kits or to test everyone’s water who asks. However the HSE’s Public Analyst Lab has told me that they will test water for lead for a fee of €10.

Soda Bottle Rocket - Make:
you can use 2-liter carbonated drink bottles to build an inexpensive, reusable water rocket. The thrill factor is surprisingly high, and you can fly them all day long for the cost of a little air and water. It’s the perfect thing for those times when you just want to head down to the local soccer field and shoot off some rockets!

Irish Water responds to landlords’ questions
ugh, what a mess....
* Every rental unit in the State is to get a pack addressed personally to the occupant. If Irish Water does not have details of a tenant, the pack will be addressed to ‘The Occupier’
* Packs will only be issued to individual rental properties in so far as Irish Water is aware of them
* Landlords can contact Irish Water to advise they have let a property
* Application Packs are issued relative to the information on the Irish Water mailing list. If this is incorrect or out of date, landlords can contact Irish Water to have the information adjusted
* Irish Water will contact known landlords after the initial customer application campaign, to advise of properties for which no application has been received
* Irish Water said that when a household is occupied the tenant is liable and when vacant the owner is liable. Both should advise Irish Water of change of status to the property - the tenant to cease liability, the landlord to take it up.
Either party may take a reading and provide it to Irish Water, alternatively Irish Water will bill on average consumption, based on the date of change.

There is NO spare capacity for Dublin's water supply
The problem in a nutshell is that for an uncomfortable amount of the year the demand outstrips what the system can comfortably supply. In the graph below you’ll see the red line (demand for water) matches and regularly exceeds the blue line (what’s produced).

Pruney fingers grip better : Nature News
The hypothesis, from Mark Changizi, an evolutionary neurobiologist at 2AI Labs in Boise, Idaho, and his colleagues goes against the common belief that fingers turn prune-like simply because they absorb water. Changizi thinks that the wrinkles act like rain treads on tyres. They create channels that allow water to drain away as we press our fingertips on to wet surfaces. This allows the fingers to make greater contact with a wet surface, giving them a better grip.'
