A 10 ohm quarter watt resistor is used as a smoke cookie igniter by applying 12V across it, which causes it to ignite.
(Note the use of a traditional quarter watt, 10 ohm carbon film resistor. These burn better than metal film ones.)

how much time it take to ignite
@misterroboto You'd be better with a beefy high current battery pack like 8 x AA cells to supply enough current to smoke the resistor. You could theoretically use something like a glow plug, but the very nature of pyrotechnic compounds means that they have a strong oxidising effect on any igniting element. Quarter watt resistors are less than a cent each, so they can be treated as a consumable.
And yet so strangely pleasing!
10 ohms not 10K. The 9V batteries might have too high an internal impedance to supply the required current. Use a beefier 12V supply.
That's nothing compared to the smell of the smoke cookie!
The commentary is the best… "So easy… Yet so strangely pleasing." That's gold, man! GOLD!
