This is seaweed.
It's very sensitive to light.
We use different kinds of light
to observe how it changes.
I hope

This is kelp.
Can I have it?
What do you want this for?
We're having a barbecue at the guesthouse tonight.
I'll add it to the menu.
If you like it, take it.

Make sure you come tonight.
Of course.
Bye.
