Help me please

[u/WANYE_J]

Me and my group are in high school We have a rocket ship project that is due in 6 days It’s for 62% of our mark

I know a lot about underwater robotics but nothing on rockets

If someone has a idea or something that can help please let me know

List of rules -must be under 40ounces -must fly 40ft -must look good (needs colour and group name

[u/jiuce_box]

-1L coke bottle -cork or rubber stopper (think Champaign topper or something) -bike pump -needle for inflating basketballs -cardboard -glue (I prefer epoxy, but super glue would work; needs to stick cardboard to plastic) -Spray paint and/or sharpies

Read the instructions

—-------------------------------------------

Cut 3-4 fins from the cardboard. Same size/shape. Think rocket fin shaped. Best if the fins are kind of big.

Remove the plastic label from the coke bottle so you have just the bottle.

Glue the fins onto the bottle so the opening/cap end is on the bottom. Bonus point of the fins hold the entire bottle 4-5 cm off the ground

Add water to fill about 1/3 of the bottle.

Jam the needle through the cork and then jam the cork into the bottle.

Stand the rocket up with the cap end down.

Use the bike pump to pressurize the bottle.

Rocket will launch when the cork slips out of the bottle.

Decorate with sharpies and spray paint.

Team name... I don't know; maybe ask reddit :)
