How to Fix Your Time Machine
As folks know, we opened the Fire, Ice and the Rise of Life exhibit this spring. We’re so excited to have the gallery open and with a fresh face!
When we design new exhibits, we think about the story, the look and feel of the space, the flow of people, the life support for the animals, the lighting, the interpretive programming…and we think about how best to reach people with different learning styles, backgrounds, reading levels and attention spans. People are often shocked to know that our signage is written at a 6th-8th grade reading level. Your local paper is written at about the same level. We try to present information in text, with a graphic AND often as a tactile manipulative experience (people can move the parts and experiment). Live animals count as an interactive experience too. The next time you’re in one of our newer exhibits, see if you can identify these different parts.
In Fire and Ice, one of our central themes is the exploration of geologic time. Have you thought about space and time? It can be a pretty mind boggling. It’s important to the story we tell in the exhibit that people do think about this. We planned on engaging people with geologic time in four different ways: through snap-shot stories in text, an outstretched arm graphic timeline, a narrated video and the hands-on manual operation of the “Time Machine”.
“Wait.What Time Machine?”

And here’s why it still looks like this.
One of our goals was to re-use or re-purpose components of the original Origins gallery whenever appropriate. Three cheers for re-using and recycling! The time machine exhibit was one of those selected to stay as a compliment to other exhibit content. Remember those four engagements with geologic time we talked about?
As the exhibit project rolled along, the re-installation of the time machine seemed like it would simply require relocation of the exhibit structure, fresh paint and a quick reprint of the graphic belt. We should have known. We’re old pros at curve balls in exhibit design and construction…”hmmm…this tank won’t fit in the elevator”… It turns out that this “simple” re-install is not so simple after all.

When the exhibit was first installed (circa 2000), the paper belt kept slipping. There wasn’t enough friction between the belt and the drums to move it smoothly and steadily. After some initial problem solving, folks mounted the paper onto a rubber belt (actually lightweight thermoplastic) that provided more friction. Now the belt moved smoothly! One downside is that the added thickness caused the surface of the belt to rub ever so slightly on itself as it wound around the drums. After 13 years of use, the images were hard to read.
After a bit more head scratching, our director had an idea. He once worked for the paper mill and he recalled the belts used to turn huge drums to convey the new paper. After a well-placed call to W.P. & R.S. Mars Company right here in Duluth, we now own a new 37.9 foot piece of lightweight thermoplastic to use as the grippy part of the belt!
Ok, now for the pretty part.
Sometimes stumbling blocks present you with opportunities. And that’s how we are looking at this project. We will be redesigning the complete belt, all 37 feet of it, to update the content and make it mesh with our new exhibit “look”.
