Amazing! I want to try this. Do the 2 cans need to be tight fitting? I can only seem to find 5L paint cans (instead of 4L - for the big can) where I am.
Thanks for your comment. The can needs to have a double layer structure. Air enters from the bottom and escapes through the secondary combustion holes. If there is a gap at the top of the can, air will escape from there, reducing the amount of air coming from the secondary combustion hole. The top must be tightly sealed. It is desirable that the inner can and outer can fit together. If not, use the outer can lid to cover the top. good luck.😀
Thanks for your comment. It seems that the translation is not working properly. Does Dauso mean DAISO? If so, DAISO products are only sold in Japan. Online shopping is also not available overseas.
Using silicone oil for storage is horrible idea when you light it next time. Oil like wd-40 aint good ether but less toxic than silicone. Also note how there is discoloration on the bottom, hence it will heat up so this should be placed on non burning surface and mind using this in well ventilated space even after flame had died down
