Go to the end of the airport near the museum. There is a vending 
machine located here. Click on it. You will get electrocuted, but
afterwards you will have a pop in your item bar. Click on it. You
will be able to temporarily walk extremely fast. Anytime you need
another pop, just click on the vending machine.
Note: If you first get the gloves off the counter at PetrolAir you
will not be zapped when you get the can from the vending machine.
