Step 4.
Weigh 20g of NaOH – warning, NaOH is extremely higroscopic (sucks out moisture from surrounding air and gets damp/sticky/clumpy – avoid humid rooms or do stuff quickly when handling it) – and add it to the mixture.
[WARNING] Caustic soda aka lye aka drain cleaner is highly alcalic and WILL burn your skin if you handle it like a retard. Do NOT handle NaOH like a retard and you’ll be fine. If it does come in contact with your skin immidieately rinse under a running tap, neutralise with kitchen vinegar if you want your house to smell like vinegar for whatever reason.
