help escaping column name in a migration file

My DB column is name "3gp", but the below is invalid syntax. How can i
express this in ruby?

class CreateVideos < ActiveRecord::Migration
  def self.up
    create_table :videos do |t|
      t.column :x, :integer
      t.column :y, :integer
      t.column :max_time, :integer
      t.column :max_file, :integer
      t.column :mp4, :integer
      t.column :3gp, :integer //how do this?

  def self.down
    drop_table :videos

I know it's not the most natural sounding thing in the world but is it heresy in Rails to just name it something like :video3gp or :format3gp instead of :3gp?

I would use your later suggestion as rails will attempt to create
accessor / mutator methods for this column, and method names can not
start with a number.
