This Week I Learned Glassblowing

I went from having no glassblowing knowledge to making a cup, bowl, and flower in 2 hours. This video documents how I did that.

Huge thanks to Treg Silkwood, The Bay Area Glass Institute, and Mike Boyd. BoJack Horseman, Coffee, Airports, Seinfeld, and more coming this fall to Technicality. Stay tuned.

BoJack Horseman, Coffee, Airports, Seinfeld, and more coming this fall to Technicality. Get hyped and stay tuned. Love y'all ✌

Am I allowed to be weirdly excited about this

I didn't know Wendover had a 3rd channel where he shows himself.

Fill up the glass until the water makes a very slight convex bubble over the top due to surface tension. The edges are then lower then the centre.

[enbyopossum]

Add some soap to the water to break the surface tension

[KhAnubis]

This video blew my mind.

(Yes, I literally watched through the whole video, just to see if you would make that pun)

[benjaminfraeyman]

Fill the glass with other corks and then put it in the center

[nerdwiththehat]

You answer - fill the glass the way up to the top, until the surface tension is holding the water a bit above the rim of the glass. That'll make the sides stay down towards the glass, raising the middle, allowing you to float the cork in the middle.

How did I go from watching videos on skateboarding, to this? Somehow... I actually enjoy it 😂

[Berotej]

Adding dishsoap to the water eliminates surface tension. This way the water wouldn't stick to the rim and the convex shape is gone. The Kork stays in the middle when you place it there.

Well the answer to this problem is easy. Get a smaller cup.






So the water that used to fill the first cup half-way fills this new cup to the brim and a bit more. Water still sticks, or adheres, to the glass, and when there's just a bit more water than the glass can hold the excess forms a "bulge" in the centre as the edges stick to the glass. That way cork will float to the centre as that is the highest point now.

(To be honest I knew the answer already, but still thought I'd post it because why not.)

I’d buy that cup, bowl, flower, and chewed up leaf in a heartbeat

[Skip]

My hypothesis: You could get the cork to float in the middle by filling the glass past the rim. The surface tension will allow you to keep adding water past the top of the glass, and it will create a dome of water where the cork will float at the very top (if placed extremely carefully). I'm going to experiment when I get home

[GRBtutorials]

With soap or detergent. They have surfactants that lower water’s surface tension, so the water won’t climb at the sides of the glass.

[Giftedbryan]

You can make the cork float at the middle of the glass by floating it in milk which has a higher surface tension, making it form a bubble. The cork will then flow at the top/middle.

Time to start cranking out some Prince Rupert's Drops for Destin.
And, shoutout to San Jose. Get La Victoria's and some orange sauce next time you're down here.

[lairdf]

awesome work! Nice glass. Fill your glass with oil, to make the cork float in the middle. (perhaps?)

[KevimationYT]

This is an amazing video. Mike makes amazing content and this video really embodies both of your content.

[backstept]

To get the cork to float in the middle you can fill the glass to the absolute top so that surface tension makes the surface of the water slightly higher than the edge.

[elijahwhiting]

Freeze the water and place it in the center duh
