@EcoShark2012 Sure. You have to add a solution of 8 grams of copper sulphate not too weak into a solution of 4 grams of sodium hydroxide. Then keep the product(copper hydroxide) into an ice bath. Philtrate the product and add to it about 50 ml of 30% ammonia. Then add to the product small pieces of blotting paper. When a piece it is dissolved add another one till nothing is able to get dissolved. The result should be a gelatinous blue liquid. Add it to a 10% solution of sulfuric acid. Is it ok?
@PubliosValesios obiviously to get the blue snakes you have to use a syringe in the last part and you should not add directly the blue gelatinous mass to the acid
@mrcatfacefrog I'm form Sardinia which is a region of Italy and English is not my language so that I try to do what I'm able to. About what you said I challenge you to do this video in italian and then to send it to me. Then I will accept your opinion concerning mine pronunciation in English. Greetings.
hi! I would like to ask what reaction happens when we put cellulose into the schweitzer's reagent, I would like to see the reaction written. And why do we put the blue liquid into the sulfuric acid? Why this acid especifically? And I would like to see this reaction written too.

@spotlightman1234 use some blotting paper: it's 100 % cellulose. Cut it in very small pieces. If it doesn't work ask me again. Greetings
