I recently needed to make a tentacle for a different project, I was rather pleased with the results and ultimately came up with several different ways to use the basic tentacle that I'd made. So this is a quick instructable demonstrating how to make the basic tentacle unit and then illustrating some of the things that you can do with them.
This instructable will also be my entry into the valentines contest. My wife is also pretty geeky so I'm sure she'll love the tentacle heart, but shh! Don't tell her before valentines!
As with most of my project nowadays if you can see it you can buy it, this is due to the fact that I'm currently unemployed and I have a lot of time on my hands, but also because selling little things like this, even with these minimal margins, allows me to save up for workshop improvements. So if you're not creative or you haven't got time to make your own then buy one from me and contribute towards my laser cutter/ leak free shed roof fund.
