Use this guide when you want to run a short session with Bio-Dynamics — a browser-only 3D lab linked from the probiotic articles on omid.dev. Each path below takes about 5 minutes; all three presets together fill a 15-minute workshop.
Educational model — not medical advice. Population counts, strain effects, and biome shifts are illustrative. Do not use this lab for diagnosis or treatment decisions.
Before you start
- Open the lab on a projector or share your screen.
- Leave the macro view (rotatable body) visible at first.
- Point out the dashboard on the right: integrity and inflammation meters, event log, stressor buttons, and catalog tabs (Strains, Prebiotics, and so on).
- Click a tissue hotspot on the body (or pick a region in the sidebar) to enter the micro view — zoomed tissue with moving microbes.
- Press Esc to return to the full body map.
Tip: Hover catalog items before clicking — the action impact panel previews what will change.

Session 1 — Allergy & barrier defense (~5 min)
Tied to: How Probiotics Help with Allergies
Open: playground.omid.dev/…/?preset=allergy®ion=nose
| Step | What to do | What to point out |
|---|---|---|
| 1 | Select Nose / Sinus (if not already active) | Baseline integrity and low inflammation |
| 2 | Click TRIGGER ALLERGEN SPIKE | Allergen count rises; integrity drops; event log narrates epithelial stress |
| 3 | Click HISTAMINE SURGE | Immune activity rises; inflammation follows over a few seconds (not instant) |
| 4 | Open Strains → apply L. rhamnosus | Probiotics spawn; pathogen pressure eases; inflammation drifts down as pressure falls |
| 5 | Click SALINE MIST (regional care) | Moisture restored; allergen adhesion reduced |
| 6 (optional) | Lower the moisture slider, then DRY AIR EXPOSURE | Mucus-layer thinning — secondary exploration |
Ask students: What recovered first — integrity, inflammation, or allergen count? Why might inflammation lag behind immune signaling?
Expected takeaway: Barrier stress and immune signaling build pressure; probiotics and moisture support competition and recovery.
Life-stage variant (~5 min)
Tied to: Probiotics Through the Ages
Open: playground.omid.dev/…/?preset=allergy&context=lifestage®ion=nose
Follow the same nose sequence as Session 1. The scenario text switches to early-life microbiome training framing. Highlight B. infantis and other life-stage strains in the catalog when discussing infant vs adult barriers.
Session 2 — Candida & pH balance (~5 min)
Tied to: How Probiotics Help with Candidiasis
Vaginal path (default)
Open: playground.omid.dev/…/?preset=candida®ion=vaginal
| Step | What to do | What to point out |
|---|---|---|
| 1 | Select Vaginal | Baseline pH ~4.2 (acidic, healthy) |
| 2 | Click ALKALINE FLUSH (pH DISRUPTION) | pH rises; yeast and Gardnerella spawn; integrity drops |
| 3 | Watch biofilm and pathogen meters | Correlated rise with alkaline shift |
| 4 | Strains → apply L. acidophilus | pH drops; biofilm eases; acidifying lactobacilli appear |
| 5 | Click pH RESTORING SERUM | Further acidity restoration |
Oral path (alternate)
Open: playground.omid.dev/…/?preset=candida®ion=oral
- ORAL THRUSH BLOOM — Candida patches; biofilm rises
- Strains → S. boulardii — yeast competitor; inflammation eases as yeast load falls
- DRY MOUTH (XEROSTOMIA) then Strains → L. salivarius — saliva niche restoration
Ask students: Why does alkaline pH favor yeast? What does acidification change in the dashboard?
Expected takeaway: pH and moisture shape who thrives; acidifying probiotics counter Candida-favoring conditions.
Session 3 — Biotic lifecycle (~5 min)
Tied to: Unlocking Prebiotics, Probiotics, and Postbiotics
Open: playground.omid.dev/…/?preset=lifecycle®ion=gut
| Step | What to do | What to point out |
|---|---|---|
| 1 | Select Gut | Baseline prebiotic particles and L. plantarum already seeded |
| 2 | Watch SCFA / Postbiotic and Prebiotic substrate stats | Conversion loop — fiber particles drop as SCFA rises |
| 3 | Click PSYCHOSOCIAL STRESS (CORTISOL) or SLEEP DEPRIVATION | Inflammation and immune signal rise; tryptophan support falls on gut |
| 4 | Click ANTIBIOTIC DISRUPTION | Commensals depleted; postbiotic level drops |
| 5 | Prebiotics tab → add inulin | More substrate particles in the lumen |
| 6 | Strains → L. plantarum or B. lactis | Additional fermenters seed the gut |
| 7 | Wait ~10–20 sim seconds | postbioticLevel climbs; integrity and tryptophan support recover when inflammation stays low |
| 8 (optional) | Click RELEASE SCFA BOOST (regional care) | Immediate postbiotic surge — barrier recovery |
Ask students: What is the order of the chain — prebiotic, probiotic, postbiotic? How does the event log describe conversion?
Expected takeaway: Fiber feeds fermenters; SCFA output supports barrier recovery — an educational proxy for the pre → pro → postbiotic story.

After step 4 in any session, click Copy lab link in the dashboard. Send the URL so students open the same tick, region, and biome state on their devices.
