Ok guys, I need help. I work for a Contract Manufacturer that is working to solve a problem for a customer of ours. The customer has designed a snowglobe (it's actually in a jar) with a cool little Christmas tree inside it. It's a great idea, but there are a ton of nooks and crannies that trap air inside them really really well when you insert the tree into the jar of solution (96.9% Distilled water, 3% glycerin, .1% IPA). What we're trying to do is find a way to dislodge the air from the Tree as the customer advertises them as being high quality and air free. Smacking the jar around dislodges some, but man those air bubbles can be stubborn! The customer has suggested using a vacuum system as their previous Chinese vendor had done (yes, we stole work back from China!) but the Chinese vendor is reluctant to disclose details of their methods. So we've tried various methods, but we have had no success. The customer has suggested placing the tree in the jar filled with the solution then placing that jar in a larger tank of solution and subjecting the whole thing to vacuum. The idea is that the vacuum will remove the air from the tree and the larger tank will keep air from re-entering while we remove the vacuum and complete the seal between the figure and the jar. I think they're crazy, but they insist that the Chinese vendor did it this way. Initial trials have achieved 0% success. The gauge on the pump maxes out at 30 mHg and I've left the container (a 1' tall, 8" diameter jar filled 75% with solution) under vacuum for as much as an hour (I've just been informed that the vacuum pump is now emitting smoke so I should probably hustle to check it out...). That being said, I'm appealing to those who might have a better understanding of what we're trying to achieve as the theory behind our goal is just beyond my understanding of the water/air/vacuum relationship. Does anyone have advice or can provide insight on how best to remove the air from the tree? This is an interesting issue and obviously there are financial implications for my company and our customer. We'd like to prove that we're as capable as our Chinese cometition and win one for the good guys! Please feel free to ask any questions that might clarify the situation. I cannot express how appreciating I am of anyone that would like to help!
