This is pretty inspirational. Im curious how much a setup like this must cost though? Cursory investigations into vaccuum costs seem pretty prohibitively high for a 12 year old, even most middle class parents. Very cool though.
Edit: sibling points out it may be $10k. I wonder if that price includes other equipment not shown. If not, apologies for the gross underestimation ($1.5-3k seemed reasonable - most of the equipment pricing can be looked up).
