From NightHawkInLight. In this video I reveal the secrets for making Japanese senko hanabi sparklers with a bicarbonate based powder composition. Because the powder contains bicarbonate instead of an oxidizer, it can rightly be categorized as non-flammable. In fact the key ingredient in these sparklers, potassium bicarbonate, is also the active ingredient in “purple k”…

From NightHawkInLight. Here’s a quick follow up to my last video about intercalated graphite and it’s use in intumescent, fire resistant products (seen here: https://youtu.be/8Z5RPPRS-KQ). This pipe collar uses strips of compressed expandable graphite flake with a flexible binder to wrap around pipes and seal them off in case of fire. Pretty neat. Thanks to…
