Since it breaks on impact with the target, and that’s what activates it’s magic, I’d assume the impact from the charge in the flintlock would pop it and activate it centring on the gun. Theoretically though you might be able to make a specific kind of bullet casing to reduce the force on the head while still propelling it from the charge. Ask your dm :)

Does anything break the bubble?  Dispel Magic?  Disintegrate? 

 I've seen a Strength save of 15 to escape/help someone escape it as well as dispel magic.  

 dispel magic only dispel, by RAW, spells ! this is not a spell, so no dispel magic for you.
actually there is next to nothing one can do to get rid of it. exect teleport away.

Actually, Dispel Magic can target "one creature, object, or magical effect within range" (i.e. 120ft).  Going by RAW, Dispel Magic immediately ends a spell when successfully cast and further clarifies that it similarly ends the effect(s) of a spell.  Given that the Bead of Force produces a very similar "bubble" to the effects of a spell like Wall of Force or Forcecage, it would normally function in a similar way except for the fact that the Bead leaves out a crucial line of text found in those two spells: "This spell can't be dispelled by dispel magic."

As a DM, I'd likely rule that a Bead has a DC15 dispel check to successfully pop it (or a 5th level Dispel Magic to skip the check) given that it specifically leaves out the exception to that vulnerability in the item text.  However, you could also argue that the intent of the Bead's description that reads "Only breathable air can pass through the sphere's wall; no attack or other effect can" would include the effect of a Dispel Magic being cast.

That being said, always ask your DM and don't be afraid to include your own reasoning if they disagree.  Any DM worth their salt should listen to their players and consider their perspective (to the extent that it doesn't derail your session), while any good player should respect their DM's ruling so long as they're consistent and fair.

Yes. It has to fit completely inside a 10 ft radius sphere.

dispel magic, disintegrate and any magic item or feature with the power to dispel magic can destroy the sphere

If you've got a 10' radius sphere that only weighs a pound, wouldn't that make this thing way less dense than air? I'm thinking the bubble should spend a minute rocketing up into the sky like a balloon and then it pops.

 Air is allowed to pass through it, meaning it weighs a pound, and would thus fall as fast as something that weighs a pound at that size.  One could argue that the sphere would have the effects of feather fall on it given that, but It would not defy gravity otherwise.  :) 

I am thinking of a 7th-level Druid Circle of the Shepherd with a sling. The character is a buff character to the party and this is one way to aid the group by locking in a bad guy as they deal with them. 

If someone was flying inside the sphere, could they pick it up and carry it around? This is assuming they could get a grip. If so, that could be an interesting combat scenario.

 Why would they need a grip from inside the sphere? It could be carried by either an African or European Swallow, no problem. Also, it weighs 1 pound, so well within the capability of a Mage Hand or Unseen Servant to pick up and move. 

It very specifically calls out 'creatures' as though objects would not be captured or pushed away by it.  If this were thrown at a statue, would it simply not activate?

Could you theoretically fire this from a flintlock?

 Late reply lol

Not RAW, ask your DM :)

Sniffle~ Wipes a tear of joy* That's the most evil thing I've ever heard

Isn't the Tarrasque larger then the 10ft radius?

Exactly, so it would be pushed outside of the sphere.

What happens if the bead impacts on the ground (a reasonably likely result)?  Since the ground/floor isn't a creature, but isn't completely within the area, does the sphere "push" the floor/ground out of the area meaning you then have a fully-formed 20' diameter sphere sitting on top of the ground? Given that the description says a creature inside of it can move the sphere, it would seem so but still unclear. And even if so, what if the area has a ceiling less than 20' off the ground? 

What you REALLY do with this, is cast levitate on the sphere with a enemy inside,  then have a party member run under it, and cast thunder wave. **** them clear into a new time zone...

Question, if you had monsters inside of the bead, couldn't you use the Ring of Telekinesis to pick up the bead with the monsters in it? You are picking up an object that isn't being worn or carried, and says nothing about it carrying other things inside of it.

 Explain?

Levitate only allows it to move 20 feet up per turn and thunderwave only moves creatures/objects 10 feet.
