Never Ask Whats In The Box!

I don’t know about you, but when presents start to appear in the run up to the big day, there is always a lot of prodding and poking going on! So this year why not try something different such as this shaking and growling parcel, it is enough to scare off even the most persistent kids and some adults too!

These are the essential materials required;

Cardboard Box

RadioShack 9V recording module

9 volt battery

100µF capacitor

2 short pieces of magnet wire

Hot glue and hot glue gun

According to the text that accompanies the video, this is what it is all about;

This is a fun prank to play on someone who shakes their presents. It is a box that plays pre-recorded sounds when it is shaken.
