All the project circuits use the LM324N integrated circuit (IC), which consists of quad low-power frequency-compensated operational amplifiers. The idea is simple and genius: combine par-cooked noodles, a bit of vegetable base, some raw sliced veggies, and a few seasonings inside a jar.
Most (ramen) noodles are made from four basic ingredients: wheat flour, salt, water, and kansui, which is essentially a type of alkaline mineral water, containing sodium carbonate and usually potassium carbonate, as well as sometimes a small amount of phosphoric acid. The borax reacts with the polyvinyl acetate molecules in the liquid glue to form large polymers.

You can add food coloring to make them colors but the colors only work if you use pipe cleaners! There was also a Toplabs kit by Slinky Science, which was identical, but had slightly different graphics on the box. This is a commonly used IC in electronics and found in modern instrumentation applications.


These kits often sell on eBay for a few pounds, and their price varies depending upon how complete it is. Add boiling water, wait a few minutes, and you've got yourself a lunch with all the appeal of instant noodles, but with actual flavor and freshness trapped under that lid.
Originally, kansui was named after the water from Inner Mongolia's Lake Kan which contained large amounts of these minerals and was said to be perfect for making these noodles.
These polymers are large repeating links of molecules and compounds that are chained together.
The tiny crystals are amazing and all of my friends and my teachers are asking me for them. This kit is for children aged 10 and older and consists of ten project circuits, with the intercom being the main feature.
The IC is extremely low cost and can be replaced as well as any missing resistors and capacitors.
This lets allows the new mixture to spread apart and flow and form to its container like a liquid, yet the molecules do not break apart like liquids.


Yesterday, we learned about snowflake science, how snowflakes are formed and that they are actually ice crystals.
It comes with a pair of plastic consoles allowing two children to play simultaneously each making an independent circuit. If your syllabus consists of op-amps, then this kit may be of interest to you, perhaps as a GCSE project idea.
Today, let’s do a fun lab that lets us create a crystal snowflake using borax instead of ice.
The kit does not require any previous knowledge of electronics or soldering because the construction of the circuit involves inserting wires and components into small pieces of breadboard.
