Dorm Room Dippin Dots

The inspiration for this came from the videos out there on youtube of people making dippin dots by dripping melted ice cream through a syringe into a bowl of liquid nitrogen. When trying to replicate this effect I found that it was painfully slow at producing dippin dots so I tried to come up with something that would be more suitable to produce dippin dots from melted ice cream at a higher quantity.




This instructable contains my two attempts at creating a dippin dot machine. The first one was based on the method that I described of dripping melted ice cream into a syringe. I essentially tried to automate the process of pushing the back of a syringe so that I could just set the machine up, step back, and watch as the dippin dots were made. However after completing the first device I realized that their was a much simpler and more effective way to make dippin dots quickly. The second device is just a container with a bunch of holes in the bottom and it is put over a bowl of liquid nitrogen. I will go thorough the construction of both of these devices in this instructable although I would recommend making the second device if you actually wanted to make a lot of dippin dots.

Materials:
- 2x4's I ad enough laying around to make a 3'x2' frame
- Wood Screws
- 3/8'' inch polyurethane tubing
- 4 Syringes
- Two plastic bottles
- Three 3/8'' T-connectors
- you will need a valve to control the flow (not pictured)
- 3 bowls (metal isn't necessary)
- Airtight plastic container
- Paracord (or other string)
- Ice-Cream
- Liquid Nitrogen*

Tools:
- Dermel (this was only used for cutting the metal bowl and the bottles)
- Drill
- Dewar (for holding the liquid nitrogen)*

*Liquid Nitrogen can be purchased at a local welding supply store if you have a suitable dewar
*Used Dewars can be found on ebay for relatively cheap. Some welding supply stores will also rent them to you.

This looks awesome..but I am trying to figure out why it's in the cardboard contest..:)
Awesome ible. Could you explain a little bit about storage?
I am glad that you asked about storage! To store the dippin dots after were made I put them in large ziplock bags and packed them in a styrofoam cooler with dry ice. I used a slab of dry ice on the bottom of the cooler and then in between each bag and on top of all of the bags. The dry ice kept the dippin dots cold enough so that they stayed crisp and would still stick to your tongue. If you just put them in the freezer then they will start to stick together. I have attached a picture of the Styrofoam cooler that I used for storage. You can usually pick these up at a grocery store.
