We&amp;rsquo;d bought an N30 cylinder of Helium from &lt;a href="http://www.irishpartysupplies.ie">Irish Party Supplies&lt;/a>, containing 7.82m³ of Helium - enough for roughly two launches of a standard sized 1000g balloon. Previously, I&amp;rsquo;d thought hydrogen would be a better choice, but considering it was a first launch we decided to play it safe (after having a gas seller painstakingly explain the various ways in which Hydrogen tanks can explode).&lt;/p></description></item><item><title>High Altitude Adventures - Part 2</title><link>https://jasonmadigan.com/posts/2013-04-24-high-altitude-adventures-part-2/</link><pubDate>Wed, 24 Apr 2013 21:20:00 +0000</pubDate><guid>https://jasonmadigan.com/posts/2013-04-24-high-altitude-adventures-part-2/</guid><description>&lt;p>Following on from my previous post, I&amp;rsquo;m going to go into a little more detail as to what we&amp;rsquo;re planning and what I&amp;rsquo;ve built so far - hopefully it will be of interest!&lt;/p>

I looked at it and thought it seemed like a good use of time. I got talking to &lt;a href="http://blog.danielvagg.com/blog/">a friend of mine&lt;/a> at work about the possibilites of launching something like this from Ireland. As it turned out, some people from launched successfully from Kerry &lt;a href="https://www.youtube.com/watch?v=cqGoFAts1ag">a few years back&lt;/a>.&lt;/p></description></item></channel></rss>
