We have to make a model house and I need to try and keep an iceblock from melting for as long as possible. :) Yeah I know it's impossible unless it's below 0 degrees.I just need some details on incredibly bad conductors of heatMaterials in the house that are reflective but do not conduct heatFor example aluminium foil is a good reflector but it conducts heatAlso would like to know how I could stop convection and airflow as i need 30% of my box to be window. I'm probably gonna put blinds or curtains or something.Thankyou to anyone who helped and yes there will be a best answer chosen ;)
wear rubber, and lots of it. rubber gloves, rubber jacket, if possible. it's also a very good idea to remove water near it.
Modern fire extinguishers are powered by air, nitrogen or CO2. If you mean a dry chemical type extinguisher, that would generally be sodium bicarbonate, monoammonium phosphate, potassium bicarbonate, or various combinations. Acid extinguishers have been obsolete for decades.
