Bubblegum takes a step back, wringing her hands together without noticing. "Well, I... I really must finish this." At Marceline's expression(?), she adds" Oh, it won't take that much longer. Just hold on!"
And with that she returns to her work, restarting the burner and taking out quite a variety of pliers and screws. A little packet of something gives off a faint woodsy aroma as she sprinkles it into a carefully-monitored solution boil, which simmers above a small fire. Hisses and clinks prevent the room from falling completely silent for any amount of time- but Bubblegum doesn't talk when she works. She never does. Can you imagine how unprofessional that would be?

A low hum fills the air, coming from a small device that looks something like a very tiny oven. Bubblegum calls over the noise. "Almost done!"
Taking out another torch-like instrument, switching it on, she continues to put together the project on her table. Bubblegum pulls back, frowning, though a rush of air flows out.
Frowning, she turns the power on the tool all the way up, and a gust of air is emitted with a sound like that of a hairdryer. The artificial breeze causes PB's hair to float and whip all around her face, but she doesn't seem fazed; it blows a hovering Marceline slowly back from its source.
