Guten Tag! Today ve will talk about light and how ve kan bend it.
We vill use a laser and we made some shteam to make the beam visible
Sky Lady is making steam.
Some theory with this small Wasser-filled tank.
If a beam goes from a tranzparent Medium into another...
it has an incidence angle.
0 degrees, 45 degrees, etc
The rifraktion angle gets smaller...
if the beam travels into a medium with higher refractive index.
But ve want something cooler!
We vill bend the beam along a kurve, not at an angle!
Alchemist, it is nearly tea-time. I will prepare the tray.
I take the Steam-o-trone away
We don't use zhis any more.
To bend Licht we need...
a long tank (from a fridge).
And this jug... and this...
Here I have disolved 1.5 kilograms sugar...
in 1.5 liters of wasser.
Let's pour the Zucker solution into the tank.
Now be kareful...
we must pour in 1.5 liters of plain water
but without disturbing the lower layer too much.
Pour slowly on a large shpoon.
Let'see!
Now here the refraktive index...
vill slowly and steadily change...
from one layer to the other.
Therefore a laser beam...
will draw a curve!
Ach, wunderschon !
Bending light with sugar !
But now Sky Lady is about to bring our tea!
Teabags, cups, hot water...
But where is the sugar ??
Er... Ich have used it up for my Experimenten now.
Again! Once the flour, then the pepper, now the sugar!!
But do not worry. I have here...
...a red hot pepper Extract!
Ve can use this inshtead of sugar...
and vill make a delicious tea !
Just a pinch and...
Er... hot pepper Extracten does not work...!
Shall we have Koffee instead?
Do not laugh after me, it vas an akcident.
At least now we know: no hot pepper into tea !
