This is the FastCap Babe-Bot (Amazon link). It is a 4-oz. bottle made for glue. I’ve got mine filled with wood glue. They also make a bigger 16oz. version but I find this one a little more handy.

What this does is make laying down glue a much tidier and more exact process. The way it does this is that the design feeds up from the bottom, through a spout — sorta like a fancy tea kettle. And when you’re done squeezing, you get this immediate back pressure that sucks the glue right back in the bottle, so you don’t get that messy string of glue drool.

There’s also a little cap here that stays attached. The whole thing makes me feel like a glue pro, and it only costs around $7. By using the Amazon link her to pick one up, you’re supporting me and the excellent Cool Tools.

Update 04/17/18:

A year later, and this bottle is still going strong. The thin red tether that kept the cap attached to the bottle snapped at some point, but the cap is still working without it.

What I realize now that I didn’t quite understand at the time is that the bottom-fed system makes it so much easier to apply glue to vertical surfaces. Also, it allows you to really see the bead you’re laying down without the bottle and nozzle getting in the way.

I still stand by this recommendation for anyone looking for a little more control over how they apply glue.
