         <description><![CDATA[<div>The mixture had baking soda and vinegar in it. At first there was no delay reaction, but I added less vinegar to the mixture and that seemed to help. (Before it went farther up, but I wasn't videoing that time.) </div>]]></description>

         <description><![CDATA[<div>My mixture was crushed bath bomb, baking soda, vinegar, and water. There was a delayed reaction because it took time for the  fizzing solids to build up enough pressure to pop the top off. My rocket went about 10 feet into the air.</div>]]></description>
