‘The season will be merry, and what better way to celebrate than relaxing a large Christmas tree in the living room?
One applied physics student from Delft University of Technology (TU Delft) in the Netherlands had a different view of what her Christmas tree would look like this year.
“Look, the smallest #ChristmasTree in the world!” read TU Delft mail on Twitter.
In fact, Maura Willems decided to create what could be the tiniest Christmas tree in the world.

The equipment Willems used was much larger than the wood she eventually created. The complex device was a scanning tunneling microscope, which can scan individual atoms to build small structures.
He literally works one atom at a time to study the individual quantum-mechanical properties of each atom.
In the end, Willems had 51 “big” Christmas trees, which roughly translates to the size of a DNA chain. To give an idea, it’s about human hair It spreads 40,000 times. Let’s talk a little.
Willems wood was precise four nanometers high, or four millionths of a millimeter – without counting the roof of the tree.
Look, the smallest in the world # Christmas tree!! 🎄
It consists of 51 atoms which #physics student Maura Willems removed from the perfect crystal lattice. The tree is 4 millionths of a millimeter (4 nm) high (excluding the tree canopy). #tudelfthttps://t.co/6b2NmqezZF pic.twitter.com/4uE4RHVQOf

It’s fun to see how such complex devices build a cheerful creation like a Christmas tree. It may not be extremely useful, but there is little light physical fun.
There’s not a good chance you’ll be able to buy such a Christmas ball, but here’s a list of things you can buy this season if you’re looking for a little last-minute inspiration.
