			<content:encoded><![CDATA[<p>Brennan and I completed our first science project of the year &#8211; <a href="http://www.youtube.com/watch?v=J81u63gWGcs">Falcon 1</a>.  This one demonstrated <a title="Search Google for Newton's Third Law." href="http://www.google.com/search?hl=en&amp;q=newton%27s+third+law&amp;btnG=Google+Search&amp;aq=3&amp;oq=newton" target="_blank">Newton&#8217;s Third Law</a> which says every action has an equal and opposite reaction. I think he understood a little bit because he said that as I filled it up, the air went in which force the water out and the bottle to fly. This is close enough for a 5 year old. <img src='http://www.danaedwards.com/wp-includes/images/smilies/icon_smile.gif' alt=':)' class='wp-smiley' /> </p>

<p>It took us about 30 minutes to make and takes very few things:</p>
<ul>
<li>a champagne cork &#8211; clearly we had one since it is 1/1/09</li>
<li><a href="http://www.amazon.com/gp/product/B0016D5F4Q?ie=UTF8&amp;tag=danaedwardsco-20&amp;linkCode=as2&amp;camp=1789&amp;creative=390957&amp;creativeASIN=B0016D5F4Q">serrated blade</a><img style="border:none !important; margin:0px !important;" src="http://www.assoc-amazon.com/e/ir?t=danaedwardsco-20&amp;l=as2&amp;o=1&amp;a=B0016D5F4Q" border="0" alt="" width="1" height="1" /></li>
<li>a 2L coke bottle</li>
<li><a href="http://www.amazon.com/gp/product/B0000DH8I8?ie=UTF8&amp;tag=danaedwardsco-20&amp;linkCode=as2&amp;camp=1789&amp;creative=390957&amp;creativeASIN=B0000DH8I8">transparent duct tape</a><img style="border:none !important; margin:0px !important;" src="http://www.assoc-amazon.com/e/ir?t=danaedwardsco-20&amp;l=as2&amp;o=1&amp;a=B0000DH8I8" border="0" alt="" width="1" height="1" /></li>
<li>a valve stem</li>
<li><a href="http://www.amazon.com/gp/product/B0009W7FBG?ie=UTF8&amp;tag=danaedwardsco-20&amp;linkCode=as2&amp;camp=1789&amp;creative=390957&amp;creativeASIN=B0009W7FBG">Bicycle Foot Pump</a><img style="border:none !important; margin:0px !important;" src="http://www.assoc-amazon.com/e/ir?t=danaedwardsco-20&amp;l=as2&amp;o=1&amp;a=B0009W7FBG" border="0" alt="" width="1" height="1" /></li>
</ul>
<p>If you have all of that, you&#8217;re set.  You can find the <a title="Find corks at Lowes" href="http://www.lowes.com/lowes/lkn?action=productList&amp;N=4294961544&amp;Ne=4294967294&amp;Ntk=i_products&amp;Ntt=cork" target="_blank">corks</a>, <a title="Find the blade I used at Lowe's" href="http://www.lowes.com/lowes/lkn?action=productDetail&amp;productId=12809-16878-50420&amp;lpage=none">serrated blade</a> and <a title="Find the duct tape I used at Lowe's" href="http://www.lowes.com/lowes/lkn?action=productDetail&amp;productId=156887-133-0003147&amp;lpage=none" target="_blank">duct tape</a> at Lowe&#8217;s.  I went down to the local tire store and asked for the valve stems &#8211; the store gave them to me for free.</p>
<p>Instructions:</p>
<ol>
<li>Remove the label from the coke bottle</li>
<li>Wrap the bottle with duct tape to reinforce the bottle in case of nicks / scrapes</li>
<li>Write something really cool on the tape with a Sharpie &#8211; perhaps &#8220;In honor of Falcon 1&#8243;</li>
<li>Cut off the bottle top ring with the serrated blade.</li>
<li>Trim the head of the champagne cork</li>
<li>Test the cork to make it sure it is close to fitting. This will be trimmed later.</li>
<li>Drill a hole which is slightly smaller than your valve stem to fit the style of valve stem you have.</li>
<li>Test that the valve stem fits into you hole.</li>
<li>At this point putting the valve stem into the hole has expanded the size of the cork.  You will need to test / trim the cork until it fits.  Be careful not to cut off too much or you will need to drink another bottle of champagne &#8211; or darn.</li>
<li>Once it fits in the bottle, take it out and fill the bottle 1/3 full with water.</li>
<li>Assemble a launch pad out of whatever you have. I used a bag of fertilizer and some paint cans. Ha!</li>
<li>Attach the bike pump to valve stem.</li>
<li>Pump up the bottle and watch it fly after about five pumps or so.</li>
</ol>
<p>I have save the maiden voyages of Falcon 1 on YouTube.com &#8211; <a title="Maiden Voyages of Falcon 1" href="http://www.youtube.com/watch?v=J81u63gWGcs" target="_blank">Falcon 1</a>.</p>
