Challenge / Content / Stream?

I'm a Twitch streamer and I'm celebrating my birthday in a special stream with a friend in my room.

In order to make the whole entertainment moderately good, I need challenges / tasks / content / ideas about what we do.

I've already written down a few.
-How many marshmallows can fit in your mouth

-What's in the box

-Youtube Reactions

-Flachwitz challenge with mouth water.

So I need a lot more ideas, if you have any I would be happy if you write them to me.

IMPORTANT TO KNOW: There's alcohol involved 😂😂

Whistle challenge.

Yeah, that's it.
