 Hey, welcome back to kids fun science. My name is Ken and today's experiment is the color changing spoons and bowl So I said my local ice cream shop toppings and I was filling up my favorite ice cream And I noticed as the ice cream started filling up in the bowl the bowl starts changing a different color So of course that a cocked my attention right ice cream and science to my favorite things all in one So I decided to do an experiment on this so you look in the description I'll show you where I got this the changing spoons and bowl and I'm gonna show you just a sec the science behind it Please remember to hit subscribe the notification bell and thumbs up if you like this experiment I also want to do a shout out to Atticus who is on my cross-country team You can enter into our giveaway for the three color changing spoons by liking this video and also subscribing to my channel So here I am at my local ice cream shop toppings as I'm putting my little frozen yogurt into the bowls I start to notice that the sides start changing color. It's turning from that blue to a purple I thought that was really cool only to find out that this is done by science So the two things that are favorite ice cream and science I was able to combine and I couldn't get enough of it So I'm gonna run a couple different experiments after I enjoy my ice cream And I'm gonna tell you the science behind it So really the bottom line these spoons and bowls are awesome and have you ever wondered how they work? Well today, I'm gonna investigate the basic color changing spoons and bowls and the science behind it with a couple different experiments So I was able at the ice cream place to be able to see it turn one way So what I've done here is I've actually Immodulated ice cream by putting cold water and luke warm water and you can see it will change right back So when you do dip it in the ice cream or you dip it into cold water like I have here Ice cubes and water stirred around you're gonna get it to turn the different color But once I dump that out and I pour luke warm water or even just tap water into it It's going to change the color back, which is pretty cool And you can see right there the water is a little bit full and it is amazing So there are two different types of thermochromism Inks that make these color changes possible thermochromatic liquid crystals TLCs and Luke code dies, which we're going to be talking about Ever heard of thermochromic? Well probably not as most people haven't the word comes from a Greek words Thermos which equals mean and chroma equals color So thermochromic represents the materials in the signal temperature change by changing colors in this case The color changing materials they can be found in a variety of objects such as mood rings battery testers coffee cups And yes color changing spoons and bowls, but the science behind this goes beyond with the changing colors It turns out the many materials react in other ways So in the case of the color changing spoons and bowls However, we want to look at the temperature sensitive dies Known as Luke code dies which start off as a particular color and become visible when the temperature rises or falls Luke code dies are Organic chemical that change colors when energy makes the molecules shift back and forth based on the temperature hot or cold We'll determine how these molecules will reflect the light and thrust represent different colors So as the magical these spoons and bowls appear we are afraid there is no magic to it Right simply science which allows us to have this awesome spoons and bowls every day it to enjoy So this type of Luke code dies Are a bit different than the TLCs that we talked about earlier for starters They feature more durable chemistry, right? So well known Luke code dies have been used in Coors light beer cans Remember the mountains are feature on the can when the can is at room temperature the mountains appear to be white However, when the cooled around 45 degree Fahrenheit the mountains turn blue. This was just an awesome experiment What I love about it is you can just keep reusing these over and over So it's really cool about that and so remember to answer the giveaway in and so for more information look in the description Under for Luke code dies and how it works under how stuff works I put a link in there it explains in great detail the science behind Luke code dies I covered at the higher level if you enjoyed this experiment Please remember to click thumbs up and to subscribe that really does help my channel and thanks for watching
