I’m a Scientist is like school science lessons meet the X Factor! School students choose which scientist gets a prize of $1000 to communicate their work.
Scientists and students talk on this website. They both break down barriers, have fun and learn. But only the students get to vote.
This zone is the Organs Zone. It has scientists studying health and disease in various parts  of our bodies. Who gets the prize? YOU decide!
Perhaps the closest things we have today are plasma cutters, but they are nowhere near as cool as light sabers. They are usually used for cutting through big plates of metal. They use electricity shooting through a stream of gas to create plasma which blasts away through the metal BUT it can only do this at very short distances, NOTHING like what you see in the movies.

To add, there are very powerful lasers that can function like a light saber.
The only part that we can’t figure out is how to make a saber out of it! For something to be so powerful, it’d need a pretty big energy supply (or we just haven’t found the right crystals!). And then there’s the problem of how to make it only work up to a certain distance away from the saber.
Although it’s not my field, I’m sure we have people working on it! Watch this space…

Great answer, guys!

This blog Physics.org has a nice post about light saber technology and the limitations which Yashar and Carina described.

When it happens (because it will one day int he future!) I would love to be able to use a light saber and make those cool sound effects too! 🙂
