hello this is my first ever uploaded model onto here!
all you need is a hex key more than 50 mm long and has a 3 mm -3,5 mm diameter x 2 ,string cork a football nozzle and a bike pump! hot glue the cork into the round holder, make sure the wider end faces the base, i will make feet for it soon that go int the 5 mm holes! put a bottle 1/3 full of water onto the cork with the base and cork facing upside down to keep the water in the bottle, once securely attached with the lip on the edge insert the 2 hex keys through the holes with string attached to the end, pump it up to a maximum of 100 psi pull the string and it flies off! make sure you have a big open space without people, and remember safety is the most important, please take care and have fun! also make sure the cork has a hole running through it that seals the football nozzle and bottle with minimal leaks.
