Well, throwing the bag at Gon's face wasn't something he'd anticipated, even though it does provide him with a much larger target. "... I don't know if they'll survive, so be careful when you open the bag, and if any do... We'll have our answer whether or not the potions work on you."

He does take a few minutes to scavenge some old rags from a skeleton and pack the bottles a little more carefully. "This will probably taste terrible, Gon, and I'm sorry." He hefts the bag to get an idea of the weight before he gives it a few spins, ready to chuck it at Gon's mouth on his say so.
