ACS Spring 2026 reinforced something I don’t want to forget: great outreach isn’t improvised—it’s engineered.

Taking this mindset into the next season of Science with Impact.

If you do public-facing science, what’s one lightweight way you measure real understanding vs. just enjoyment?

At ACS Spring 2026, a few moments stood out to me because they were practical, not just inspiring.

Do you prefer to author your reactive sites asset-first (as we did here in the JSON/metadata) to reduce processing, or do you prefer to calculate those capabilities dynamically at runtime via rule scripts? I'm curious about the long-term scalability trade-offs! 👇🏽

We finally cracked the physics of neutralization in our Unity engine, but it required a major architectural pivot. đź§Şđź’»

🛑 Zero proton exchange.

✅ The Fix: We refactored our architecture to be completely “asset-first.”

🟢 Now, every single unit inherently knows if it’s a reactive site.

âś… AFTER: 30 out of 70 responses successfully used mechanistic chemistry terms to explain the slime's behavior.

That is a 5x increase in chemistry comprehension. We successfully measured the transition of 24 children from sensory observers to reasoning with chemistry.

The results after they completed the slime activity:
❌ BEFORE: Only 6 out of 70 responses used chemistry-based language. The overwhelming majority (51) relied purely on sensory observations.

At the ACS Kids Zone with MONET, our goal was to move participants from describing slime as "squishy" (sensory) to understanding cross-linking (mechanistic).

We collected 70 pre- and post-activity index card assessments from participants (65 of which were children).

How do you MEASURE if your outreach actually taught the public science? (Data inside 📊👇)

The PIs I support enter Grant Reviews with more than just dates and participant counts; we also measure the depth of their broader impacts using simple assessment strategies like this Index Card Pre-Post.

Rigorous science doesn't have to be boring, and fun science doesn't have to lack mechanistic truth.

Out of all the amazing, hands-on activities at the festival, our interactive slime station won the "Most Fun" tally board vote from the kids themselves! (See the overwhelming tally marks below!)

By turning cross-linking into a game of cause and effect, the kids weren't just watching science—they were controlling it.

The best part?

The Center for Molecularly Optimized Networks (MONET) wanted to change that at the ACS Kids Zone.

We built an interactive 3D simulation that let kids actually manipulate the borate ions and PVA strands to see the "Hidden Layer" of the material.

đź”— Use the "Chemical Connector" (borate ions) to cross-link the PVA strands.
✂️ Use the "Bond Breaker" (acetic acid) to undo the network and return the slime to a liquid state.

(Pro tip: The physics engine is fully optimized for mobile, so it's best experienced on your phone!)

Want to try the interactive 3D chemistry game that won "Most Fun" at the ACS Kids Zone? 🎮🧪

We built this WebGL simulation in partnership with the NSF Center for Molecularly Optimized Networks (MONET) to answer one specific question: What exactly makes slime stretchy?

Now, you can play it yourself!

I just published a complete, behind-the-scenes case study breaking down exactly how we designed the chemistry logic of a slime chemistry game, why play-based hypothesis testing can be an effective outreach strategy, and how you can capture hard educational data for your next grant renewal.

Recently, the NSF-Funded Center for Chemical Innovation: Molecularly Optimized NETworks (MONET) and the American Chemical Society Kids Zone partnered with us at Science with Impact to see if we could turn sensory play into a measurable science lesson.

Slime is (arguably) the world’s most popular chemistry demo. But let's be honest: most kids leave the table thinking it’s just "magic goo." 🪄🧪

For NSF-funded researchers and science educators, "Broader Impacts" require more than just smiles—they require measurable learning outcomes.

"Everything is sales—welcome to your life." Academics are conditioned to feel bad about "selling," but you're always selling something—your research, your ideas, your value.
