My 8 year-old adores his John Adams electronics kit, so we were really looking forward to this. Within minutes of opening it however he pronounced it to be rubbish - and I was cross with him for being so ungrateful until I looked more closely.
Inside the box there are some cardboard shapes which can be moved around to produce optical illusions and a handful of playing cards with pretty poor and well-known optical illusions printed on them.
The 3D warthog you are invited to make needs VERY strong glue (not included) to hold it in shape, and when you've made it, there's nothing 3D about it whatsoever, and we eventually gave up wondering how it was meant to work.
One of the 'tricks' consists of old-fashioned cardboard 3D glasses and two very small and unimpressive 3D scenes on playing cards to look at. In an age where you can watch an entire movie in astonishing 3D even on a TV, this is ridiculous. Another 'trick' instructs you to get a pen with no ink in it, fill it with lemon juice, write on some paper and then heat the paper with a candle. None of these things are included.
There are two optical illusion 'posters' (A3 size I think) which you'll have seen before and aren't well executed anyway.
Luckily my son also received a different, brilliant box of science magic tricks which are seriously good, easy and no-one's seen them before - and it's ALSO by John Adams, called Science FX. Buy that one, not this.
