This is a magical 3D printed jar of RGB lights that simulates real fluid behavior
Step 1: Metal Contact

First fold the tin foil into the above shape to create 4 contact points
Step2: Installing Metal Contact

Find four rectangular holes in the 3d printed jar and use glue gun to install four metal contacts, the inside should look like this when finished
Step 3: Light Diffuser

cut out a piece of rectangular sheet of foam and install it in the inside of the 3D printed jar wall
Step 4: Install RGB Pixel Grid

wrap the 8x32 RGB pixel grid around and place it inside the jar
Step 5: Prepare the Connector Wires

Use wire stripping tools to prepare the connector wires for the RGB LED matrix
Step 6: Connect CPB

![截屏2021-10-07 下午4.43.41.png](/proxy/?url=https://content.instructables.com/F8T/0QGA/KUH8NX3C/F8T0QGAKUH8NX3C.png&filename=截屏2021-10-07 下午4.43.41.png)
- Connect RGB matrix connectors to the CPB (A1 pin)
- Connect alligator clips like in the picture (A4, A5, A6, 3.3v pins)
- Connect battery pack to the CPB
Step 7: Connection to Tin Connectors

connect alligator clips to the tin connectors at the bottom of the jar
Step 8: Put Everything Together
![截屏2021-10-07 下午4.45.55.png](/proxy/?url=https://content.instructables.com/FM1/JCS3/KUH8NXQP/FM1JCS3KUH8NXQP.png&filename=截屏2021-10-07 下午4.45.55.png)
Put all electronics and wirings inside the jar (note the orientation of the CPB)
Step 9: Close the Lid
![截屏2021-10-07 下午4.48.12.png](/proxy/?url=https://content.instructables.com/FGK/J6P1/KUH8NYEK/FGKJ6P1KUH8NYEK.png&filename=截屏2021-10-07 下午4.48.12.png)
Close the lid and complete the build, now we will need to create another same jar again
Step 10: Uploading Program - Host End
Choose one jar and upload this program to the PCB on it
Downloads
Step 11: Uploading Program - Client End
Upload this program for the PCB on the other jar
Downloads
Step 12: Tinfoil Layout

Layout tinfoils on a piece of cardboard like this
Step 13: Complete "refilling" Station

- cut holes for the water faucet on another piece of cardboard,
- install the water faucet
- and finally put everything together
