This morning while brushing I found myself wishing I had one of those plastic toothpaste tube squeezer thingies (the technical term).
I checked Amazon and the ones I liked were about $5 each. I also wasn't happy about bringing extra plastic crap into our home. So I thought about how to make one.
Lego construction seemed a promising route.
This should work equally well for other tubed materials like sunscreen, makeup, oil or watercolor paints, etc.
Teachers! Did you use this instructable in your classroom?
Add a Teacher Note to share how you incorporated it into your lesson.
Step 1: Pieces
Find the 4 required Lego technic pieces. They are:
-2 bars with holes, at least 9 holes long for a standard tube. Longer is fine.
-The critical pins that my son the Master Builder calls "threes." These pins have one end that fits securely into a bar's holes. The other end has a double-long section that the bar can slide on. This lets you adjust the distance between the bars.
Step 2: Assembly
Put together with enough space between the pins to accommodate your preferred tube. Mine was at the ends of a 9-hole bar. It doesn't seem to matter if the pins are oriented the same or swapped.
Step 3: Use
Voila! Nudge the bars apart, insert tube, and squeeze together. The bars make a surprisingly effective squeegee and stay where you leave them, forcing the remaining toothpaste to the spout end. Have fun and thanks for reading.
