where do you get the bike valve ,can you post several to me at malaysia?

[sciencetoymaker]

@afiq8219 I'm puzzled.Auto part stores might not be common, but there are automobiles in Malaysia. Find a person who fixes tires.

[afiq8219]

i already make the upper of the rocket launcher and i cant find the find the bike valve in hardware store.yes you ve said that thing cant bought at autoparts but my country dont have one .i watched Kipkay and he uses ordinary recycle bike valve and scrath the rubber ,can i do that so

[sciencetoymaker]

@afiq8219 Yes, whatever works to get the air pressure inside the pump.

[afiq8219]

can we make the rocket model to an airplane model?

[sciencetoymaker]

@afiq8219 Yes, but I expect there would be a lot of experimenting to actually get it to fly well.

@afiq8219 salam bro, kalau tak jumpa terpaksa beli inner tube tayar satu, lebih kurang RM15 la so kalau boleh try cari kedai kereta pastu beli valve tayar tanpa tiub

@afiq8219 haha salam bro. saya dari malaysia juga. kalau tak dapat cari terpaksala beli inner tiub tayar satu. ~RM15. ak sebab tukar tayar bocor dulu sbb tu ada extra. tak pun try cari kedai kereta tengok dia ada tak jual valve tayar tanpa tiub, murah sikit

also i prefer you to dont duct tape extra pipe(leftover)because it will tear or non - stick after 10-20 use cause not water proof (sticky part)unless you has one(special one)you can hose clamp or glue(waterproof)

[afiq8219]

i already do 3 of those with varios type of size,small works great and theirs an issues, i found each bottle has it own size,mineral water has big and small ,soda ;coca cola has the big mouth,(in malaysia)F n N;sometimes big but sometimes small ,so i have to put in hot waterto shape i it up, can you study this problems?
