INVENTION CONVENTION---ROCKETS!

The weather COOPERATED! We has GREAT FUN today designing and launching different types of rockets. All of the kids made rockets out of 2 liter bottles and launched them using a very simple launcher (pvc pipe and a bike pump), it was so much fun to watch the rockets take off and gain height and then fall back to the ground! Jacob didn't do ANYTHING to his 2 liter and of course, because it was the lightest, it went the highest! We also experiments with vinegar and baking soda and also alka seltzer tablets as "rocket" fuel! One of the families brought a HUGE water powered rocket and the boys had a great time trying to figure out how to get it to launch.....when it finally took off, half of us weren't even paying attention any longer because it had taken so long for them to get it to launch!

Friday April 8, 2011 at Miami Riverview Park
In April we will be making and launching rockets:

Items needed:
film canisters (I have pretty many of these, but if you have some laying around please bring them)
alka-seltzer tablets (would someone like to buy a box to bring?)
I will bring vinegar and baking soda
2 liter soda bottle (minimum of 1 per rocket, can use 2 per rocket)
foam core, cardboard or balsa wood to make fins and nose cone

Film Canister Rockets: I would like to do both alka-seltzer rockets (http://www.sciencebob.com/experiments/filmrocket.php) and baking soda and vinegar rockets (http://pbskids.org/zoom/activities/sci/filmcanisterrocket.html) these should only take a few minutes to make and launch!

This is the launcher I wanted, but at the last minute the family who said they would make it backed out http://www.pbs.org/kcet/wiredscience/video/330-geekdad_soda_bottle_water_rocket.html so I ended up making this launcher instead, http://users.soe.ucsc.edu/~karplus/abe/soda-bottle-rocket.pdf, it worked, but not like the first one would have--or so I suspect! Also a word of warning...the PVC glue STINKS and is expensive for what you get, I think I might try gorilla glue or super glue if I made one again!

We also made some "stomp" rockets as well, these are super simple and would be quite entertaining for a kids birthday party as a craft to keep the kids busy! http://familyfun.go.com/crafts/build-a-bottle-rocket-906453/

How can this specific conserve the long lasting wellbeing of the online game?This particular factor is when I must accept the city. I believe that the particular “precious metal tax” won't sufficiently kitchen sink your rare metal fast enough when compared to the fee in which it is actually being injected to the sport. We actually usually do not even think the particular precious metal kitchen sink arrive near to countering procedure prices if your numbers Jagex given to people are genuine.
