Marry Porter: Hi! I'm Merry Porter from the Curiosity Zone. Today, we are doing simple hands-on science experiments that you can do with little kids, with the things that are all around your house that focus on energy and how we use energy to make thing move. So, our next experiment is going to be using an acid-base reaction that creates a gas that's going to blast off a rocket. Your ingredients are, first of all, a film canister and the kind of film canister you want is the kind that secures on the inside as opposed to the outside. They are usually white. You need sheets of foam that you can cut out to make parts of your rocket, you need a hot glue gun and glue gun sticks, you need some tape, you need effervescent tablets or Alka-Seltzer and you need some water. First step in making your rocket is to take a piece of foam and wrap it around the bottom of your rocket. Make sure you cut enough that it wraps around a little bit, so you can glue it in the place. You make a little mark, and then you have to decide, how tall you want your rocket to be. I'm going to make mine relatively short because a shorter rocket will actually blast off, a little bit higher because it has less weight on it. So, we are going to wrap this around like this, at the base and then we are going to hot glue in place and be careful with the hot glue that you don't burn yourself, that sometimes happens and this is a good thing for a grown up to do for kids because it gets super hot. If you prefer, you can always just tape it together. The nice thing about the hot glue is that once it gets wet, it will hold in place, whereas the tape sometimes comes off when it gets wet. So, now we've made the bottom of our rocket and you can see that's where the fuel is going to go, and then you are going to clip the bottom in. So, the next thing you want to do is create the nose cone and the fins. If you want fins, you can decorate any which way. Today, we are just going to do a little nose cone and the best thing to do is, just basically cut a circle. If you want to be super neat about it, you can trace out a circle using a cup or a bowl or anything round and I'm just going to kind of freehand this. You basically just want to cut a big circle, like this, and then you are just going to cut a slit, right up to the center like this, and then bend it around like this and glue it. You can see how that creates a little nose cone. So, I'm going to glue this in place now or you can tape it or staple it, whatever works for you. We will glue this in place and hold it, until it gets nice and firm like this, and then we are going to attach it. Now I have kind of a pink leopard rocket which is a kind of cool, and now I am going to glue the top on just by putting hot glue around the tipi-tipi hot top like this. I'm going to glue that right on like that, you need to give it the second for everything to just kind of gel. Alright, now, that's basically how you make your rocket and you put the bottom on. Once you have made your rocket, what you need to do is make your rocket fuel and that's really what this experiment is about it. It's fun to do arts and crafts, but really this experiment is about creating energy and the way we are going to blast off this rocket is to create an acid-base reaction that gives off a gas. And as the gas starts to increase in size, it's going to densely pop the lid of the bottom and it's going to go, poo, it going to all the way to the ceiling, alright. So, the way we create our acid-base reaction is using effervescent tablets. We are going to put one of these in here and it doesn't take much to pop the top off of a film canister. So, we are going to just take a little, maybe a quarter of a piece and we are going to put it in the bottom, and then we are going to pour a little bit of water in and you want to make sure the kids are wearing the safety goggles, before you start blasting anything off. So, here we are going to cause our acid-base reaction. Here we
