a corny question...

tomorrow I will be helping with dinner for a small program ( only 10 people)that helps homeless families; the way it works is we preapare food at home, then bring it to a church and serve it. I will need to leave home at 430 , arrive at the chutch  at 5 , serve at 6 ( the doors will not be open before 5) . I would like to bring corn on the cob , but cannot figure out how to do it; since the church only has a small electric stove , I am afraid a big pot of water will not boil in time - also cannot imagine how to do it at home by my usual method and transport it....maybe I should just do frozen kernels- thanks for any help.
