How to generate electricity from salt and water and glow up an led

🧂⚡ I Made a Saltwater Battery That Lights Up an LED! | Rbot Boy

Hey fam!
Ever thought salt and water could power something?
Well... guess what? I tried it — and BOOM — I made a working saltwater battery that lit up an LED 😳💡

No big setup, no crazy parts. Just home science, full Gen Z engineering.

🔧 What I Used:

  • Salt 🧂

  • Tap water 💧

  • Two different metal plates (I used copper and aluminum)

  • Small plastic cup

  • Wires

  • One LED bulb

🛠️ How I Built It:

  1. Filled the cup with water and mixed in a bunch of salt. Stirred it like chai. ☕

  2. Dropped in the two metal plates (they act like battery terminals).

  3. Connected each plate to a wire.

  4. Touched the wires to an LED… and boom 💥 — light!

  5. I taped everything to hold it in place and showed off to my fam 😂

🔍 What I Learned:

  • Saltwater becomes a conductor and lets electric current flow between the two metals.

  • The chemical reaction between the metals creates electricity 🔋

  • You don’t always need batteries — just creativity + science = POWER

This was hands-down one of the coolest tiny experiments I’ve done.
It’s easy, fun, and actually works.
If you ever want to feel like a scientist + inventor, give this a shot.

Built with salt, sweat, and swag,
— Rbot Boy

🏗️💧 I Built a Hydraulic Excavator Arm at Home (Using Injections & Pipes!)

Hey, it’s me, Sintu — a teenager who loves building stuff instead of just watching reels all day 😅. Recently, I built something super cool : a working Excavator  arm that uses hydraulic power . No motors. No batteries. Just water, pressure, and some jugaadu creativity. Here’s how I made it 👇 🧰 What I Used to Make My JCB Arm I didn’t buy any fancy kit. I made it with easily available stuff (and some from the local medical store 😆) 🧩 Item 💡 Use 6 Injections (Syringes)    For creating the hydraulic push-pull action PVC Pipes           For making the frame and structure Plastic Pipe / IV Tube         For connecting the syringes and transferring pressure Wires        For joints and extra strength Water       The actual fluid to create hydraulic pressure 🛒 Similar stuff on Amazon (you should buy them for every robot): Pipe for hydrolic pressure PVC sheet for bod...

Hello World! A Teenager’s Introduction to Robotics

  Welcome to Rbot Boy: My Robotics Journey Begins! 🤖 Hey there! I’m Sintu, and this is my first ever blog post on Rbot Boy . I’ve started this blog because I’ve a strong interest in robotics , and I thought — why not share my journey while I learn? I’m a teenager, and I don’t have any fancy coaching or classes. I just explore stuff on the internet, try small experiments, and learn by doing. It’s not always easy, but it’s a lot of fun! Why I Made This Blog 🛠️ I’ve always been curious about how machines work. When I saw videos of small robots doing cool things — like avoiding obstacles, following lines, or even picking up stuff — I got super interested. Since I’m just starting out, I thought maybe other students like me might also be searching for simple ways to learn robotics. So this blog is like my notebook — but public! You can learn with me, side by side. What You’ll See on Rbot Boy I’m planning to post: Basic stuff I’m learning in robotics Simple projects wit...
