Teacher Notes

Teachers! Did you use this instructable in your classroom?
Add a Teacher Note to share how you incorporated it into your lesson.

Step 1: Materials

I used a very cheap electrical tape because you will need the whole roll. I used a glass jar because I don't know how well plastic will hold up to the vacuum. The tube I use is vinyl. The tube should fit snugly on the funnel and the fitting on your vacuum pump.

Step 2: The Build

Wash your jar and remove label. Push tube over funnel. Tape to hold tube tight. Tape roll of Electric tape to the funnel. Make sure that you don't tape over the hole.

Step 3: Using

Push tube over fitting on your vacuum pump and put the funnel end on jar. Turn on pump and push funnel on the jar to make a seal. Let go and use. Please tell me in comments what you think.

    I used to do this, though I would wrap the jar in tape in case of implosion.. I highly recommend stopping this, getting a nice chamber and spending the cash.. One of these can very easily turn into a bunch of glass powder. Believe me you don't want that.
