Creating a water dispenser working model using a water bottle and cardboard involves simulating the mechanism of a simple water dispenser.

Below is an explanation of how to construct and understand this model:

Materials Needed:

1. Empty water bottle with a cap
2. Cardboard
3. Craft knife or scissors
4. Drinking straw
5. Small plastic cup
6. Hot glue gun and glue sticks
7. Small piece of sponge or absorbent material
8. Marker
9. Decorative materials (optional)

Construction Steps:

1. Base Construction:
   • Cut a rectangular piece of cardboard to serve as the base for the water dispenser.
2. Bottle Holder:
   • Cut another piece of cardboard to create a holder for the water bottle. This holder should be wide enough to accommodate the base of the bottle and tall enough to stabilize the bottle.
3. Attach Bottle Holder:
   • Use a hot glue gun to attach the bottle holder vertically onto the base. Ensure it is securely fixed and stable.
4. Bottle Placement:
   • Place the water bottle into the holder, securing it in an upright position.
5. Straw Insertion:
   • Cut a section of a drinking straw and insert it through the bottle cap, ensuring it is long enough to reach the bottom of the bottle.
6. Cup Holder:
   • Cut another small piece of cardboard to create a holder for the plastic cup. Attach this holder near the bottom of the base.
7. Attach Cup Holder:
   • Use the hot glue gun to attach the cup holder horizontally onto the base.
8. Straw Extension:
   • Extend the other end of the drinking straw outside the bottle, positioning it above the cup holder.
9. Sponge Placement:
   • Attach a small piece of sponge or absorbent material to the end of the straw outside the bottle.
10. Decorate (Optional):
    • Decorate the water dispenser with additional cardboard shapes, colors, or any decorative materials you like.

How It Works:

1. Bottle as Reservoir:
   • The water bottle serves as a reservoir, containing the water that will be dispensed.
2. Straw Function:
   • The drinking straw inserted through the bottle cap allows water to be drawn from the bottle.
3. Sponge as Dispenser:
   • The sponge or absorbent material at the end of the straw outside the bottle functions as a dispenser. When the straw is pressed down, the sponge absorbs water and dispenses it into the cup.
4. Cup Collection:
   • The plastic cup placed in the cup holder collects the dispensed water.
