Discover why your finger works on touchscreens but your glove doesn't—it's all about electrical conductivity
Educational content slides
Humans are 60% water, and water contains ions.
Ions are charged particles that conduct electricity. Your body is basically a walking conductor!
When you touch a screen, you're not just pressing—you're completing an electrical circuit.
Your finger = conductive bridge between screen and ground
Test your understanding with this quiz.
You try to use your phone with winter gloves. What's the problem?
Complete this exercise and get AI-powered feedback.
Now that you understand conductivity, think about real-world problems it creates—and how to solve them.
Consider: Medical, industrial, artistic, accessibility, environmental contexts where standard touch doesn't work.
