- most common design you will see.

Anybody go to the summer institute and get an idea of what the rules will be like??

Lots of minor changes that address various safety and competitive concerns we had. The major change is using 1L bottles instead of 2L bottles.

Shriek!! 1L bottles, guess the times will plummet this year, and im gonna have to cut the weight balance system in half. Still no parachutes?

My friend's brother did bottle rocket (apparently his brother is in ESO, but IDK if that was an event in ESO) with a 1-liter bottle...he said the bottles were extremely hard to find. But I'm looking forward to seeing everyone's designs at competitions!

That's a concern I had too (but was overruled on). Supposedly they are pretty common in gas station convenience stores.

You could've used 20 ounce bottles?

I should have been a little more explicit. The rules allow 1L OR LESS size bottles. So a 20 oz bottle is permitted.

Every grocery store in the country has 1L carbonated bottles, but they might not be in the soda aisle. Carbonated flavored water, club soda and tonic water are all most commonly sold in 1L bottles and are generally stocked with the other bottled water, near the sports drinks and energy drinks.

There is actually much more variety in 1L bottle shapes than 2L, which could lead to interesting designs.

YUP, Ive gone to Grocery Stores and Conveience Stores and there are TONS of 1L bottles, they are mostly all the same design as the 20oz Bottles, but look a little bigger

Some gas stations sell 1L pop bottles that are shaped like 2L.

Ah, so it's not a typo.
If I have something attached to my rocket by string, does this violate the rule of "not changing shape?"

Depends...if the string was deployed during the flight then yes it would but if you just had the string randomly attached to the bottle before/during the flight then no.

i have a question is it a violation to have the fins of the rocket to be iverted
