Water Kit©Contents

  • 24 Oxygen* Pieces (Used to Assemble 12 Water Molecule Models)
  • 24 Hydrogen* Pieces (Used to Assemble 12 Water Molecule Models)
  • 1 Chloride* (Chlorine) Model
  • 1 Sodium* Model
  • 2 Carbon Pieces (Used to Assemble 1 Ethane Model)
  • 6 Hydrogen** Pieces without Magnets (Used to Assemble 1 Ethane Model)
  • 1 Post (Used to Assemble 1 Ethane Model)
  • 1 Hydroxyl* Group Model (Preassembled)

Embedded Magnets in North & South Poles*North and south poles on embedded magnets simulate the partially positive and negative charges of oxygen and hydrogen atoms, and chloride and sodium ions.

Hydrogen Piece**The hydrogen pieces for the ethane model do not include embedded magnets, since ethane is nonpolar.

Assembling 3D Water Molecules

Assembling Two Red Pieces Together

1. Take one red piece in each hand. Find the post and hole on the inside rim of each red piece.

2. Align the post and holes of the two pieces and push together until they fit tightly.

Assembling an H2O Molecule

3. Take the red oxygen atom in one hand and one white hydrogen piece with a magnet* in your other hand.

4. Push the two pieces together until the hydrogen fits tightly onto the oxygen.

5. Repeat with a second white hydrogen piece with a magnet.

Complete Water Molecule

You now have one complete water molecule model. Repeat with remaining parts until you've built 12 water molecules.


Assembling 3D Ethane

Folding a Gray Carbon Piece

1. Take a gray carbon piece and fold the three sections together until it is completely closed.

Attach a Hydrogen to a Carbon Piece

2. Attach one white hydrogen piece without a magnet** to one of the knobs on the carbon.

3. Repeat with two more hydrogen pieces.

Combining Two Carbon Pieces

4. Turn the carbon until you see the hole on one side. Take the other carbon, press the three sections together and insert one of its knobs into the hole of the first carbon.

5. Attach the three remaining hydrogen pieces to the knobs on the second carbon piece.

Inserting a Gray Post & a Hydrogen Piece

6. Insert the gray post into the last white hydrogen piece.

7. Insert the post (now attached to the hydrogen piece) into the hole of the second carbon.

Ethane Model

You now have an ethane model.


Assembling 3D Ethanol

Change Ethane to Ethanol

1. To change ethane into ethanol, first locate the hydrogen with the attached post. Look for the hydrogen that is surrounded by three tiny triangular bumps (see black circles on photo). 


Assembling Ethanol

2. Remove the hydrogen with the post and insert the exposed knob on the preassembled hydroxyl group into the exposed hole on ethane model.


Ethanol Model

You now have an ethanol model.
