Put your lighter in the ice box, you will lower the pressure in the lighter, run some water in the sink, get it hot not scalding hot and put the butane can in the water you are building vapor pressure, it doesn't"t take long, about 5 mins, take lighter out the ref and fill put it down and wait 5 mins and refill again, most people don"t realize that the butane is in an air-conditioned house, and you have been handling your lighter hence the vapor pressure is up, believe me you will get a lot more butane in the lighter this way.
