Assuming that 'cold' means normal room temperature, then heat would flow from your finger to the water.
When you burn your finger, it most often happens when you touch somethinghot, and the heat transfers to the skin by conduction.A much better example of burning yourself by radiation is sunburn.
DefinitionThe cold stimulation test for Raynaud's phenomenon is a test that measures the temperature of each finger after they are placed in an ice-water bath.How the test is performedA heat sensor is taped to your fingers and the temperature is recorded. Your hand is then immersed in ice water for 20 seconds. Then it is removed from the bath and the temperature recorded every 5 minutes until your finger temperature is the same as it was before the bath.How to prepare for the testNo special preparation is necessary for this test.How the test will feelThere may be some discomfort while your hand is in the cold water.Why the test is performedThis test is a screening tool for Raynaud's phenomenon.Normal ValuesNormally your finger temperature will return to normal within 15 minutes after the cold water exposure.What abnormal results meanYou may have Raynaud's phenomenon if your finger temperature takes greater than 20 minutes to return to pre-bath temperature.What the risks areThere are no risks associated with this test.Special considerationsThis test should not be performed if you have a finger infection or problems with the blood supply to your fingers.
If the beaker has a cold water, or something else cold, in it than the heat that is in our finger will run out of you finger into the cold water. This leaves your finger 'empty' of heat, giving you the sensation of being cold. You need to remember that only heat moves. When you are cold you wear a jumper that keeps the heat in your body, not keep the cool out.

Put the finger in water, temperature 100 - 104F.
Because your finger doesn't give you a number for temperature. And also, if the liquid is quite warm, it can burn your finger obviously. The thermometer on the other hand is made to deal with extreme temperatures, unlike your finger. It gives a precise, almost accurate reading of the temperature.
You get fingered
it hurts
you use your finger

When you type alot your finger pads can wear off. Then your finger prints aren't very defined.
