Quick, Fun and Cheap!!
Ratios are not Crucial, I would say 2:1 Methanol to borax...
Now the Methanol can be purchased at most Auto store or local stores with an Auto section sold under the name of "HEET" it is made for us as a water remover from gas tanks, and is widely available. Make sure you buy the Yellow one and Not the Red one, Yellow is Methanol while the Red is nothing more then isopropyl (Rubbing Alcohol) which will not work because the borax can not displace into the solution properly to produce the green flame effect.
Other then that it's about a simple as mixing it up and lighting, though I do go a little more into detail in the video above, hope you enjoy!
