Paper Globe of Slide Together Hearts

I ran across an intriguing globe made of slotted triangles on CutOutFoldUp, a sort of ditrigonal icosidodecahedron.  I thought it would be interesting to see what it would look like with heart shapes rather than triangles.  This is what I came up with. 

The perfect polyhedron valentine "card" for a math lover?

If you use 5 different colors it is possible to construct a model in which no two hearts of the same color connect to each other.


Can be hand or machine cut.

How to construct the slotted heart globe

Cut a total of 20 hearts.  I used 4 each of 5 different colors.

Lay the hearts out on the table.  Check that they are all right side up--that the slots are all in the same orientation.

Slot together 5 hearts, one of each color.  I slotted the tops of the hearts together on this round.  (Slot 1 slides into slot 2.)

It should look like a star.

The colors are, clockwise, in this order: green, orange, pink, purple, blue.

For the second round, I slotted the next row to the first row, point-to-point.

Working around clockwise, slot a blue heart onto the pink heart, add a green heart to the purple, an orange heart to the blue, a pink heart to the green, a purple heart to the orange.

Third Round.  I attached these top-of-heart to top-of heart.  In the photo below the hearts are laid out between the hearts they will attach to.

Green attaches to purple and blue of the second round, orange hooks to blue and green, pink goes on green and orange, purple goes on orange and pink,  blue goes on pink and purple. 

When you have finished adding this row the model is starting to look like a ball.

Last round, point-to-point again.

Add the pink to the point of the green heart from the third round, purple to orange, blue to pink, green to purple, orange to blue.

Join the tops of the hearts of the last row, in the same way the first row was joined, forming a star.

The model is now a ball.

Neaten everything up by pushing together any slots that are loose, and you are done!
