Well here's a cheap and easy way ...go to a beauty supply store and ask for a pump for a gallon container, they have them for shampoo, they are usually about $1.99 -$2.99 ...and that's the way I do it
if you want to move it to a smaller bottle and u have trouble getting the last of it out just cut it open and use some kind of stick or knife to scrap the last of it out. yea the pump will make it easy to transfer.
