I’ve gathered up some common household ingredients and a frying pan because
ingredients and a frying pan because
ingredients and a frying pan because today we’re doing some kitchen chemistry
today we’re doing some kitchen chemistry
today we’re doing some kitchen chemistry this is the type of cooking that gets me
this is the type of cooking that gets me
this is the type of cooking that gets me excited because I’m trying out recipes
excited because I’m trying out recipes
excited because I’m trying out recipes for solid state rocket fuel
to get started I’m taking this portable
to get started I’m taking this portable electric burner outside and away from
electric burner outside and away from
electric burner outside and away from anything flammable I’ll add a frying pan
anything flammable I’ll add a frying pan
anything flammable I’ll add a frying pan and set the heat to medium-low this lid
and set the heat to medium-low this lid
and set the heat to medium-low this lid should help it heat faster and while
should help it heat faster and while
should help it heat faster and while that’s warming up I’ll place one of
that’s warming up I’ll place one of
that’s warming up I’ll place one of these plastic cups on a digital scale
these plastic cups on a digital scale
these plastic cups on a digital scale and turn it on when the scale is zeroed
and turn it on when the scale is zeroed
and turn it on when the scale is zeroed out the weight of the cup I’m ready to
