Haven't watched the videos (laundry), but I'm wondering.... Any bicycle pump has a check valve. What happens if you just revere that. Pull up to suck.

Schrader valves are one-way!

WikiHow says that you can just reverse part of the bike pump. Are they oversimplifying? Everyone else has a few more steps!

You know, there is a cheaper way. Have you ever inflated a mattress, pool toy, etc., without a pump? Here! Watch this awkward video!
Someone pointed out that foot pumps for air mattresses are often reversible. This one is $12.21, but Harbor Freight's transfer pump is $7, although here is a coupon for $3 off.

So just run the Schrader valve backwards....

Why are we doing this vacuum exercise anyways unless it is the instant marinade technique.

Most horse supply places have up to 100Cc syringes that you can buy but without a needle
Or make a plastic pipe pool soaker, but you'll be limited to low vacuum
