Step 1: Whats Available
measure around 1 to 2 inches and cut the straw in a 30 degree angle so it will look like it is slightly leaning.
Unscrew the lid of the new fluid bottle. There should be a seal to prevent leakage before it gets to the hands of the end-user.
Important thing is: DO NOT remove this seal. You will need it to glue the short straw on. It is also to prevent any poisoning should any of your colleagues decide to have a sip.
Thats really all. from this picture you can see the straw appears to be sticking out of the seal as if it was punched in. I'll leave it there until later in the day when I top up my gearbox.
