*says "lets jam" to strawberries*
Is that a threat? XD

Fun video! I'm slightly disappointed that "playing with cats" wasn't one of the options for the coolest use for lasers. 😂

[hollowayar]

I was literally taking a drink of some nice cool water when you said that it might be dinosaur pee....Really enjoy your videos and how fun and enthusiastically you present everything! Keep up the awesome work.

Careful there physics girl, you’re drifting into the wonderful world of chemistry.


Who am I kidding. We’re always happy to have more visitors.

When she starts doing interviews with fruits, you know that she's been in quarantine way too long.

The ap "ToneGen" will let you add quite a few frequencies together. Even lets you choose between sine, triangle and square wave for each individual tone.

"Let's jam!"
The sound of casually threatening to murder your berries.

3:34 *boat won't go up and down. And that sound experiment was awesome.*

Disclaimer: never ever use a medium power laser without protective goggles, and especially don't shine it into reflective or refractive surfaces or objects, as invisible parts of the spectrum that weren't filtered out correctly could reflect into your eyes, and blind you without you even noticing it.

For me, when a girl smart is a complete happiness, to listen and discuss something interesting. In the age of social networks and instagram, it is very important to have someone with whom you can discuss it. Thank you Dianna for interesting videos:)

I came for the science and stay for the puns. <3

[neilbrideau]

These are not the science experiments we deserve but they are the experiments we need.

[mratanusarkar]

Haha... I just can't stop laughing!
Damn! Those are some smart Fruit Puns!!
Keep going Dianna... and Happy Physics-ing!

Great video! As the drop falls off the ice cube it's in free-fall and no longer being held up by the boat. So the boat will rise up a little bit in the water. Once it hits the bottom, the boat is supporting its weight once again, so it will go back down to its original level. The same will happen with the next drop. So the boat relative to the water will basically be alternating between two equilibrium positions. But because the water doesn't have that much damping the boat will actually oscillate around each equilibrium position-- overshoot it a bit, and then come back down a bit too far, but a little bit less on each cycle as energy dissipates.

First thing that went though my mind when I saw a laser was *laser* *rated* *goggles...*
Which was not present during the entire video... Please be safe and protect your eyes when playing with lasers.

I love the "disco" boots. Have you got that in a hat or maybe disco sandals or perhaps in a nail polish? I am so bored here at home that I did all my nails in 20 different colors. All my finger and toe nails have a different colors. Seriously I love your experiments.

[khurramsaeed]

thank you form Pakistan
For making our days a little more fun while we are all stuck at home

[TienAnta]

I’m gonna guess your second contestant’s name was “melon-ie”?

All amazing experiment's! Congrats

1:35 lasers were invented so we could watch a kitten catch a red dot.
