When I started this project in 2005 there were very little resources for my students to use.Natorshttps://www.blogger.com/profile/08518217337235939701noreply@blogger.comtag:blogger.com,1999:blog-5110801721211207950.post-81789500447720141142013-10-07T12:38:06.473-07:002013-10-07T12:38:06.473-07:00How much water did you use in the one liter bottle...How much water did you use in the one liter bottle? I built a lawndart style rocket, it weight 117.2 grams with fins and all. I used a water bottle (16.9ounces) and achieved a around 8 seconds with this lawndart style. I am now building the coney rocket, and its all built perfectly except for the fins...I am making those from balsa wood and will attach them later tonight. I was just curious as to how much water to put in...Thanks! :) Anonymoushttps://www.blogger.com/profile/08115966446606388589noreply@blogger.comtag:blogger.com,1999:blog-5110801721211207950.post-67062837814573976142010-02-20T05:41:09.224-08:002010-02-20T05:41:09.224-08:00Very nice.

When it missed it usually meant a smashed nose cone.<br /><br />I like the idea of just stable enough, and have it coming down side ways.<br /><br />Thanks,<br />Brian <br><a href="http://www.tooele-homes.com" rel="nofollow">Utah Horse Property</a>sls1jhttps://www.blogger.com/profile/01294556624028049856noreply@blogger.com
