Anyone else from ireland!!

[pink13penguin]

Hey, well I'm Cian or pink13penguin.
I'm from Balbriggan in Dublin, Ireland!! Wter rocketery isn't the most popular hobby here in Dublin!! I'm actually just 16 but became interested when I entered the B.T. Young Scientist and Technology Exhibition in 2008 with a project entitled To find the optimum structure and contents of an unmodified water rocket to achieve its highest apogee!! I became amazed at the whole maths and physics that I began applying to each launch, and in the end I was presented first in the chemical, physics and maths category. I was presented with the overall junior northern ireland young scientist and the Institute of Physics in Ireland award. After that, I continue to apply my maths and physics to launch results to imply the best launch!!

Steve,

You're right! Cian has quite a long list of achievements under his belt! It's great to hear that water rockets are attracting such high caliber people from all over the world!

Cian,

Welcome to the Water Rocket Forum! Great to have you join us here! We look forward to interacting with you!

Isn't Galway in Ireland???

[pink13penguin]

Galway sure is in Ireland - the beautiful west coast!

[pink13penguin]

Sorry, That's Galway in New york!!!!! !!!!!!!!!!!

There's a Galway in the west of Ireland aswell!!!!!!!!!!11

Welcome Cian! I want to ask you how you got your nickname? Are you a Linux Guru or something?

[pink13penguin]

Linux guru - no sorry. I was always the pink penguin!! I always wamted to see a pink one! When I first subcribed for something Pink Penguin was taking so I threw a number between and pink13penguin has always stuck since then.

Do you have those really thick bottles in Ireland, Cian? They hold more pressure. What is a typical burst pressure of a bottle you typically use?

[pink13penguin]

No our standard bottle is just a regurlar continental bottle as far as I'm aware from. I pressure tested one to 130 PSI (9.14017 kg/cm). I wouldn't dare to go over 130.
However, we do have these 750ml bottles which the plastic is about 2 mm or there abouts thick.

If that helps?

Hi Cian,

What is the purpose of the 750ml bottles? In the States we have some bottles I found that are thicker than the regular soda bottles. The thick ones are used for beer. They hold more pressure but the drawback of them is they have "decorative" shapes and patterns molded in which make them hard to use for anything and I think the patterns make them weak at those points. I believe beer bottles in general have more pressure inside so the thickness makes sense for this purpose.

[pink13penguin]

The 750 ml bottles are used to contain a soda drink (pepsi). They don't have much decoration on them as far as I know.

Later on I will post a picture to clarify this.

Cool! Do you have any idea why the Pepsi bottles would be extra thick?

Hi Cian,

Your not the only one from Ireland, Ilive over in good old Donegal, and have just been co-opted across from the Yahoo water rocket board, and the IWRA.
Thanks for the email David.

As for the bottles over here, You can get the 75cl bottles that are used by Schwepps for tonic water etc. They are blown from the same pre-form as a standerd 1 ltr bottle, but becuase they are on 75cl the wall thickenss is much greater, around 1.2mm. These are good and safe for repeated 120psi launches and lawn dart landings. I have flown some of them more times than I can remember, and there still going strong after 3 years

Try to get the older bottles, the ones with the dimples on the neck, the new ones are realy thin walled, cutbacks you know, less PET to pay for.

If you only have thin walled bottles do the trick of shrinking one bottle over the outside of another. In one statick test on a 2ltr bottle I took it upto 380 psi, and still couldn't get it to fail, great for CO2 lauches.

Any way, all the best
