Reed & Caroline – Dark Matter

It’s “Reed & Caroline Wednesday” again. 😉 The VeryRecords recording artists’ music is a part of my Yuck Science virtual programs, and there will be an extra post each week January featuring one of their songs.

Dark Matter is a track from their second album Hello Science. In addition to being a catchy tune, this features a simple but very creative paper animation made by singer Caroline Schutz’s daughter Ava. Does this video give you any ideas for what you could create?

This style of video is called stop motion animation. All it takes to create is a camera and an idea! Ava took photos of her creations with a story in her mind. There are several photos per second, and they were edited together into an animation.

Keep in Touch!

Do you have a science question, or a question about something from one of our shows?

If you have a science question you would like to have answered either in a comment or possibly featured in a future post, leave a comment and ask! I hope you will understand I do not correspond privately with children, but I am very happy to answer any questions in any public post!

Do you want to be among the very first to see new blog entries or science videos?

You can enter your email in the subscription area of this page to the to be among the first to receive notices about new posts here! Your personal information will absolutely never be sold or used for any other purpose. Or you click on any of the social media links on this page and follow us on those sites as well!

Do you have an idea for a future post or video?

Student’s ideas are a big part of the shows, and I would love to hear yours. You can leave it in the comments below or on any Yuck social media page. If you include your name and school, you will be recognized if your idea is used.

Do you have a fun science project or art you would like to share and possibly be featured in this blog?

I love seeing students’ work! A few students have already had art related to the shows shown here, and I would love to use more! Or if you have a cool science experiment you have done, I would love to share your work with others! Please have a parent send photos or a story to so that we can make sure we have permission to post your material.

Do you want to see the latest videos and photos from the shows?

I’m not going to lie, I think the photos and videos on the Yuck Instagram account are some of the most fun on the whole internet! And the science videos at Yuck Science on youtube or the hundreds of slime and cream pie videos from past shows at YuckTV are a lot of fun, too. Or maybe facebook and twitter are your thing, and you can find Yuck there, too!

This has been a really exciting year for Yuck, with our new Yuck Science show, new public science video series, and finding new ways to stay in touch with all of our friends at schools through this blog and other social media. Thanks so much for reading and participating in science!

A Popsicle Stick Chain Reaction!

I’ve gotten a lot of questions about how to make your own popsicle stick chain reaction after featuring a small chain in the Yuck Science video program.

How to Weave Your Sticks!

First off, while I have the most fun calling these popsicle sticks, they are actually jumbo craft sticks, more the size of tongue depressors like a doctor uses, measuring 6 inches by 3/4 inch. You can try regular popsicle sticks, but they are thicker and work less well.

“Open your mouth and say, aaah!”

Step 1.

Make a tic-tac-toe shape out of four sticks. The sticks are colored so that you can see how they cross easily.

Step 1

Step 2.

Add a cross piece that weaves between three of the sticks. This holds that end in place. Keep a hand on the other end or your chain reaction will happen early! This happens to everyone a few times while they learn. Don’t get frustrated! Soon you’ll be a pro!

Step 2

Step 3.

Continue by adding a stick that weaves between the two sticks on the bottom.

Step 3

Step 4.

Then add a stick that crosses the last one you added, weaving between two of the sticks as well.

Step 4

Step 5.

Keep going! Add a stick that crosses the last one you added again. If the sticks you are supposed to weave through don’t have enough length for your new stick, you may need to move them over. I almost ran out of room here!

Step 5

Step 6.

Keep going! You should be getting the hang of it now, but if it takes some time, be patient with yourself! It can be tricky to master! To stop, add another cross piece on the bottom, like the red stick you added in Step 2. This will allow you to take your hands off!

Step 7.

When you are ready to start your chain reaction, remove the first stick!

The Science!

What’s happening here? The sticks are bent and woven together, which creates tension. That tension is called stored energy or potential energy. When you release the stick from the end, the tension is released making the sticks fly through the air. This movement is called kinetic energy.

Kinetic energy is the energy of something in motion. That’s a big word for a young scientist, but you are more familiar with it than you think! Your PE coach studied kinesiology in school! That’s the science of exercise and body movement. Do you see the similarities in the words? Both start with the letters KINE! That comes from an ancient Greek word kinēsis which means . . . movement or motion!

Working with popsicle sticks shows potential energy and kinetic energy very simply. Bending the popsicle stick “stores” potential energy until you convert it to kinetic energy by releasing it. It almost sounds like too many words to describe something so simple, right? But there are tons of real life applications!

Roller coaster designers study potential and kinetic energy all the time!


A fun application is a roller coaster! Roller coaster designers think about potential energy all the time to calculate how much energy is needed to move a roller coaster car through a track in a fun and safe way! At the tippy top right before a big drop, cars have their highest potential energy. As they fall, their potential energy falls as their kinetic energy increases, maybe even enough to propel them up another peak!

The roller coaster might move along the track endlessly as potential and kinetic energy balance back and forth, but other factors make it lose speed, requiring designers to know the right places to help carry the cars back up to the next . . . BIG . . . DROP!

Right before a roller coaster car drops, it has its highest stored or potential energy. When it is moving its fastest in the bottom of the drop, it has its highest kinetic energy.

Souvenir Merchandise

Yuck Game Show t-shirts and other merchandise are available through Cafe Press.  These items were made available for the kind folks who ask for souvenir items.  The prices are set by Cafe Press, and I have opted to receive any of the money from purchases to keep prices at least somewhat low.
