Is there a way to make an ink that appears from the heat or moisture of a persons hand?

Lemon juice or even milk can be used as ink. When heated by an iron or light bulb, the ink will turn brown. It doesn't necessarily disappear when cooled off again. There are other chemical inks that will fade out with the cooling off, but I don't know their availability to the commercial market.

Where does the heat and moisture of hurricanes come from?
The heat and moisture comes from warm ocean water. The heat that warms the ocean water ultimately comes from the sun.
What is sensible heat without moisture?
Sensible heat is the heat required to raise the temperature of a substance. When determining the heat of a vapor, moisture must be considered as it removes heat from the vapor (in order to heat the moisture [water vapor] to the ambient temperature). Dry steam has no moisture. Dry air has no moisture (a physical improbability). Air normally has moisture determined as relative humidity. This humidity [water vapor] must be heated with the air. Then the moisture heat absorption must be subtracted from the whole to determine the heat absorption of the air without moisture, expressed as heat per unit per degree (often 0.24 btu per dry standard cubic foot per degree F for air). Any moisture in the air increases the heat necessary to raise the temperature by about 1 btu per pound of moisture per degree F. (0.004 btu per gram of moisture per degree F). This increased heat requirement becomes more evident as air is compressed, and the moisture is removed by condensation.
Moisture is to humidity as warmth is to?
heat
Which type of the heat transfer is moving heat from the pot handle into the person hand?
Within the pot handle (solid) heat transfer is by conduction. Within a persons hand heat is transferred namely by conduction. Heat convection does occur by motion of the body fluids but it's slower. When you grab the hot handle of a pot you can immediately feel the sensation of "hot".Heat conduction is the mechanism responsible for this fast transfer.
What makes crystallization happen?
Heat and Moisture.
How does heat affect a compost pile?
Heat and Moisture break down the compost.
Why does Ac work but heat is on too?
The AC runs to remove moisture from the air inside your vehicle. Moisture causes the fog inside of your windows. The ac runs to remove the moisture and the heater runs to heat the air.
Above all leathers are sensitive to what?
Heat and moisture.
Can something speed the process of mold?
Heat and moisture
How do you clear internal moisture in double glazing?
You can try the same method used to clear moisture from an analogue watch face, heat. There are a couple of ways you can apply the heat, from a lamp, or a heat gun. Be careful with a heat gun that you do not melt or damage the frame. Keep in mind that the window is a sealed system, so the moisture (condensation) may return.
Why is moist heat efficient than dry heat?
Conductivity. Moisture conducts the heat better than a dry system.
What happens to air's moisture and heat content?
