HOW TO REVEAL SUBATOMIC PARTICLES AT HOME
Materials
A jar
A sponge
Rubbing alcohol
A flashlight
A black marker
Some dry ice
A subatomic particle (There are plenty of them shooting all around us and through us)
Procedure
1.Stuff the sponge in the bottom of the jar
2.Pour some rubbing alcohol on the sponge
3.Color the inside of the lid black using the marker
4.Place the lid on the jar
5.Pour out a pile of dry ice
6.Place the jar upside-down on the dry ice
7.Wait several minutes for the lid to cool down
8.Shine the flashlight over the lid
9.Turn off all other lights and look closely for a line of small droplets to appear
These lines consist of a cloud of droplets formed when muons or electrons from the cosmic shower shoot through the supersaturated vapor of alcohol, disturbing it enough to cause the vapor to condense into a cloud of liquid droplets. Every line you see in the jar comes from a different subatomic particle.
THERMOCHROMIC BABY UNDERWEAR
Thermochromic materials change color due to a change in temperature. Baby underwear is one of the multiple applications of this property in the textile industry.
1.Get a thermochromic product https://rapife.com/en/5_termocromico
2.The drawings are silkscreened using thermochromic pigments
3.When the baby’s temperature is below 38ºC, the drawings are visible
4.If the baby increases its temperature above 38°C the drawings disappear warning that the child has a fever
