Doing a PhD comes with many different experiences. GUTS PhDs Tatvan Todor and Ethell Dubois experienced science communication in a unique way, by being on stage with the Hoe?Zo! Show. In this blog, they give you a glimpse behind the scenes!
“So, there you are. A scientist on stage, spotlights in your eyes. You look at the garden gnome. And then you look back at a room full of extremely curious 9- to 10-year-olds, all eagerly waiting for you to explain how love works.
And you have five minutes.
That, in a nutshell, is the Hoe?Zo! Show.”

The Hoe?Zo! Show
The Hoe?Zo! Show is an interactive theater show for children aged 9 to 10, who get to ask questions to scientists. Prior to attending the show, a course is provided to inform the children on scientific research. In multiple classes, they learn how to distinguish fact from fiction, form a research question, assess sources on trustworthiness, run an experiment, and how to discuss scientific findings with different audiences. During the show, children get the opportunity to ask a scientific question to the scientists on stage, who then have to provide an answer by working together and using props in support of their explanation. Together with the shows’ presenter, Boy Vissers, the scientists use their improvisation skills and creativity to attempt to successfully respond to the question, all while remaining understandable for 9- to 10-year-olds. A unique but very fun challenge! The Hoe?Zo! Show was developed by Barbara Braams and Lennart de Groot in 2019. More information can be found on the official website: https://hoezoshow.nl/.
Well prepared for improvising
Before we faced a room full of curious 9- to 10-year-olds, we actually had two full days of training. And it turns out there is quite a lot to learn when your job is to explain science on the spot, preferably while holding a random object.
We did theatre and improvisation exercises, learned about how children learn and process information, practiced turning our own PhD research into a short and understandable pitch (for Tatvan, that meant using a Mona pudding as a brain; for Ethell, demonstrating trust by having Boy fall backwards into her arms), and trained how to answer completely unexpected questions using whatever props we were given.
The challenge was not just to get the science right, but to explain it in a way that was fun and engaging for the children, and fun for us too!
And those training days were also about getting to know each other and building a good group dynamic, because that dynamic translated directly onto the stage.
“So, basically, we were learning to think like scientists, explain like teachers, and improvise like actors~ while becoming a bit of a theatre group along the way.”

The discomfort of uncertainty
As researchers, we are constantly trying to make predictions. We make hypotheses for our research questions, we try to anticipate all possible things that can go wrong, and we do our very best to avoid (statistical) uncertainty. All of this goes out of the window once you are on stage with the Hoe?Zo! Show, with questions varying from animal to universe, from toenails to infinity. This discomfort of uncertainty forces us to grow outside of our professional comfort zone. By sharing this exciting experience with other young scientists, we swiftly grew closer to each other.
The group of scientists consisted of 14 PhD students from various disciplines, to ensure a broad realm of background knowledge was present on stage. Each show, up to six scientists were challenged to respond to three questions in ten minutes. Despite having a neuroscientist, an astrophysicist, a chemist and a hydrologist present, children’s questions could still reach beyond the scope of our knowledge. Despite improvising theatrically, we must provide as correct of an answer as possible. That’s where our handy-dandy tablets came into play.
Considering, as Boy would say; “the scientists know a lot about one thing, but not everything about everything”, we were allowed a brief Google-search on the topic of the posed question. We learned the concept on stage and immediately had to explain it a minute later in accessible language. Although we struggle initially, we eventually manage to come up with an explanation and theatrical use of attributes supporting it. This type of creative challenge is unique to the Hoe?Zo! Show!
A stage to learn
Besides from teaching children about scientific research, we also learn a lot from being on stage. Once, during Tatvan’s introductory pitch, she mentioned teenagers asking whether anyone had an older sibling. Lots of hands went up, until one girl suddenly shouted: “My brother smells like sweat!”. Instead of continuing the planned pitch script, she went with it, continuing her pitch: “… besides the physical changes, like the ones your brother is going through, there are also changes in behaviour, which is what I study”. The girl in the audience had made Tatvan’s pitch more fun and relatable, teaching us to let go of the script, listen to what the children give you, and build on it.
Another interesting moment happened in another show, following a question regarding why our eyes look red on flash photos. During the explanation, a boy in the audience was desperately raising his hand, wanting to add to the explanation. After the show, he came up to Tatvan and explained that some animals’ eyes instead glow green due to a reflective layer behind their retina enabling visibility in the dark. In that moment, he had taught me something, while more importantly reminding her of how exciting it is to learn something, making new knowledge your own, and eagerly sharing it with others.
This enthusiasm for science that can sometimes get lost in everyday routines, was brought back by working with these children.
A lasting impression
The respected interdisciplinary field of science communication became even more meaningful to us. Every year, young scientists travel all throughout the country to be on stage with the Hoe?Zo! Show. From Assen to Breda, and from Amsterdam to Doetinchem, all kids are welcome to learn about scientific research.
A goal of the Hoe?Zo! Show is to prove that science is for everyone, and a scientist does not come in the form of, as Boy would say; “an old white man in a labcoat”. We believe that teaching children scientific and critical thinking skills should be done from an early age already. Children should be encouraged to take the risk of asking a question and learn to trust that it will be well received. But the curiosity? Children already have plenty of that. And sometimes, they are the ones who bring that curiosity back to us as scientists and adults.
Taken together, we thoroughly enjoyed being part of the team of the 2026 Hoe?Zo! Show and would highly recommend all PhD students to go outside of their comfort zone and learn science communication in a very unique way. This experience confirmed for both of us that science communication is something we want to pursue, perhaps in more surprising ways than anticipated.
The 2026 season of the Hoe?Zo! Show is not over just yet. You can see us on stage on the 16th of October 2026 in Franeker, Theater de Koornbeurs, and on the 25th of October in Utrecht, TivoliVredenburg. For more info and tickets: https://hoezoshow.nl/speeldata.
