W: Not everything about Halloween has to be dark and scary. It can also be green and eco-friendly. Join us today is Danny with his great ideas. He is a living green contributor for Better Homes and Gardens. Hello, Danny!
   M: Happy Halloween to you!
   W: The same to you, Danny. Let’s start with your solar power ghosts.
   M: Yeah. We can all have solar lights and they are super energy-efficient because they use the power of the sun to charge up. So why not take an old bed sheet and look at what I’m gonna do. You hang it over the solar light. You take a little shape, and draw on it the face of a ghost. Look, you’ve got an illuminated ghost. So at night, when the sun goes down and solar lights turn on you’ve got these glowing ghosts hanging in the trees.
   W: Oh, so beautiful! That’s how it looks like. That’s pretty awesome.
   M: Yeah, very gorgeous! It uses the power of the super energy fission lights in a very creative way.
   W: OK, let’s talk about those little ghost lights. These are LEDs, right?
   M: Yes, this is the newest thing right now. LED stands for “light emitting diode”. So basically these lights are like regular string lights. But they are gonna last 25,000 hours if you plug them in.
   W: What?
   M: Yeah, for three years they will stay illuminated. If you plug them in today, three years from now, you have to unplug them because they will finally burn out.
   W: That is wonderful! OK, let’s go over to the jack-o’-lanterns. Then once you put candles in, you recommend using soy candles.
   M: Yeah, soy as we know is good for the environment, because it is made from renewable soy beans. It’s not paraffin-based and it’s really inexpensive now.
   W: What about the price?
   M: Comparing its price with that of regular candles, if you think about how long they are actually gonna burn, you’re gonna save money in the long run.
   W: Well, what will you do after Halloween with your jack-o’-lantern?
   M: Actually we recycle the pumpkin as a planter. You should never throw away your pumpkin, because believe it or not, all those seeds if you throw them in the landfill, they actually begin to grow, so they are having problems with the vines. Yeah, and it is actually horrific for the landfill. So you actually should chop it up and bury it in your garden if you can.
   W: That’ a good idea. All right, let’s talk about your recycling cartons. That’s a great idea too.
   M: Well, you like our egg cartons here? Great! Cut a shape with the cartons and use some black paint, and you can actually make these scary little bats.
   W: All right. They can be recycled and they are a little scary. As always, it’s nice to see you.
   M: Thank you. Happy Halloween.
   W: Thank you.
