My new friend…. :)

I have finished building my Newton’s cradle tonight. Here it is:

                                           Nice package!

                                            Yeah!! I’m done 🙂

As other Newton’s cradles on the market, its structure is quite simple- a couple of planks, a few strings and some metal balls. In this one, the package comes with marbles and you’ll have to use your own super glue and sticky tape to fix them onto strings. Don’t know how long they’re gonna last but it’s cheap for sure. What can you ask for with 105 yen in Japan?
