Put on your detective hats! 🕵️♂️ Investigation Step 1
Can You See Germs?
Clue #1
With Our Regular Eyes
Hands might look clean and tidy. But tiny germs are invisible to human eyes!
"They're too small to see!"
Germs Love To Hitchhike!
They jump onto hands when we touch toys, doorknobs, and the floor. They want to travel to our noses and mouths!
"Sneaky travelers!"
💡
Detective Question: How can we see what is invisible?

GLOW Revealed!
Look at fingertips, fingernails, and thumbs glowing neon!
✨
Look closely: Where are the brightest glowing spots?
Under nails & between fingers!
Can Water Alone Wash Them?
The Big Test
Water Alone 💦 Quick Splash
Germs are sticky like oil! Cold or quick water just slides right over them.
❌ Result: Hands STILL glow bright under the light!
Soap & Bubbles 🧼 The Superhero!
Soap bubbles grab onto germs and pull them off skin so water can rinse them away!
✅ Result: Germs get trapped in bubbles and flushed down!
Soap needs time to work! We must scrub for 20 full seconds.
