As I move from building base modules into making terrain for my micro RC car track I have been developing ideas for terrain on each module. There are some obvious ones such as using paper mache or building jumps out of cardboard or wood but I found an interesting product at the Australian Toy Fair that piqued my interest. It was called ‘Kinetic Sand’.
The idea of using ‘sand’ with micro RC cars that are in the form of buggies, desert trucks and rally cars seems only logical to me.
This video shows what you can do with Kinetic Sand.
So naturally what I wanted to know is can I make this myself. I researching the possibility I found that Kinetic Sand is not something that can be made easily at home, but what can be made is what is refered to as ‘Moon Sand’. There are many recipes out on the web for moon sand and they are typically a mixture of play sand, corn flour/starch and water in around a 4:2:1 ratio (there are many sites with recipes but the pictures I have seen for this one appears to be a good consistency).
There are pros and cons to using home-made moon sand vs the newer, polymer based kinetic sands.
Home Made Moon Sand
Pros – Can make at home, cheap to make, safe
Cons – Will dry out (although can be reconstituted), water based so may not be compatible with RC car electronics, can be crumbly so may get into RC car running gear, clean up may be difficult
Commercial Kinetic Sand
Pros – Won’t dry out (polymeric ingredient), safe
Cons – Not sure if polymer ingredient (Polydimethylsiloxane) will be compatible with all parts of the RC cars, expensive, sand may get into RC car running gear
With either type of moldable sand I am really not sure of the compatibility with micro RC cars and what effect it could have on them. I think I will still make a small batch of Moon Sand to see what it is like. If I don’t like the home made Moon Sand then, after a little more reasearch on the polymer ingredient, I may fork over some dollars on the Kinetic Sand. Even if I don’t use it for the Micro RC Track it still is fun to play with!
