if your on a decent length journey or you're going to be out and about for a while... relentless probably isnt the best thing considering the size of the can... more drink = more trips to the toilet :lol:
I like the idea of polystyrene... but i thought it might end up breaking up and making a mess all over the car once its been used a few times. rubber or foam may also be a good idea... but its finding some that would be big enough and cost effective enough to make it out of...
i even thought of using a normal sized can... but cut the top off and then fill inside with something around the reb bull can to get the mould of it, then use sand paper and increase the size slightly so the can fits in and out better... main problem with this idea is that the top edge of it will obviously be sharp...
just wondered if anyone had had this idea before and come up with something thats works, or even if there is an adaptor in production... might have a look in the tacky section of halfrauds and see if i can find anything there 😃
