You could probably use rubbing alcohol as well ( Isopropyl alchohol, Isopropanol) which is easier to get. Also keep the alcohols cold (in the freezer).

Very cool. When we do this at The Tech Museum we use Gatorade so we don’t have to add salt and room temperature rubbing alcohol from the grocery store. Works great with adults, only OK with kids (too few cells? maybe cold rubbing alcohol would help?). And in the take home handout, we describe it as snot floating in alcohol.


[...] Who knew so many people busy themselves extracting DNA at home? [...]
