"The next thing you want is something so incredibly easy. My piece of tape, my helium balloon, helium has an atomic number of two. Go ahead and tape this to show that's helium. Now I'm going to go ahead and tape the last thing, and now this is something your dad, your mom or your gardener does, fertilizer. Three different types of combinations from the periodic table make up fertilizer. There might be even a little bit more that's in there but these are the three main ingredients. Put three strings, let's go ahead and let's start off with nitrogen which has an atomic number of seven and I'm going to go ahead and put this over here and start off with seven. You can see this is five for boron, six for carbon, seven for nitrogen and then the next one I'm going to look for is going to be potassium. That has an atomic number of fifteen, oh actually its phosphorus so I'm going to put Phosphorus right here, capital "P" to show phosphorus. You can see the string leading to it and the third and final ingredient is potassium and that actually has a short hand symbol of "K" and that has an atomic number of nineteen. So if you look over here as far over here there's potassium. So you've connected up all your items that have to do with the elements in our everyday lives."
