- This was from Davina from Magnolia,
hey, again, from Magnolia Middle School in Joppa, Maryland.
Thanks again for watching.
How can you remember the difference
between a stalactite and a stalagmite?
Wait, wait, wait, it's my time to shine, hold on.
So here we go. (laughing)
So stalactites are the ones that are hanging tight
to the ceiling, all right, you can picture that?
They're holding on tight and they're hanging down,
whereas stalagmites are the ones
that might get big and tall one day
from the drips that are falling down on them, all right?
Yeah, I had one, ow! - Yeah.
- All right, then I have another one online.
This is from sixth-grade students
at Mesa View Elementary School in Grants, New Mexico.
- That's a-- - what kind of equipment
do I need to explore caves?
- So, well, you gotta start with a helmet,
you gotta protect your head, right?
And then you've gotta have boots on,
we've all got boots on today.
Gosh, what else would you need, el--
- Three sources of light. - Yes, three sources of light,
elbow pads, knee pads, in case you have to crawl
like we talked about earlier
and, very important, you should always have other people
with you, not just by yourself.
You should go in a group of people.
- I appreciate that you always bring back the importance
of the people in caves, it's not just the resources,
it's the people that are all brought together.
- It's a team. - They might help you
get out out of cave. - Yes, in case you get lost.
- [Woman] Yes.
