50 Optical Illusions (Usborne Activity Cards) (Puzzle Cards no pen)

These were a stocking filler for my 7 year old but he’s been fascinated with them and looks at them every day!

These Usborne Optical Illusions cards are intriguing and attention-holding, with a certain mind-bending 'cool factor', making them of interest to curious kids, teens and adults alike.Some cards demonstrate that you cannot trust what your eyes are seeing! For example, two colours in a picture appear different but are in fact the same, or apparently over-lapping circles are not really overlapping at all. A 'revealer card' is included, which features a ruler edge and two holes to view colours through seperately, to prove certain illusions are true!There are 50 illusion cards, approx 15.5cm long, boldly coloured and with explanations of the illusions on the reverse of each card. Not every card is mind-blowing but there is a decent variety and overall this set makes up an interesting collection. Ideal for dipping in and out of, for travel and for showing friends.

Great fun, big cards, nice print at the front and the explanation of the illusion at the back.

The optical illusions are fascinating and just a little bit freaky, though some of them left me feeling a little travel sick. I enjoyed them at least as much as my seven (and a half !) year old nephew for whom they were bought. The quality of the cards and printing is also first class, so even his favourites, which he insists on showing all visitors, are still looking new. Great product, no criticisms.

Nicely presented box of illusions. The pack has the most well known ones and fun to discover new ones. Had considered books but we love the pack where cards can be shared around friends. My son is 9, and could see the illusions, 6 year old friend struggled with some.

These are great fun, my son loved receiving these as a present; gave me a headache!

Some interesting illusion cards, others not as good but on the whole a nice little set for those interested in magic and illusions.

Ordered as a Christmas present for a family member. Delivered within 24 hours of being ordered and some very clever tricks on the eyes.

Muy chulo, a mi hija de 7años le chifla. Me gusta el texto en inglés que necesitan leer para comprender cada carta, lo leen con ilusión para saber cómo interpretarla.

Fun product

Quality product and great illusions. I highly recommend it.

Ich habe schon viele Bücher zu diesem Thema. Hier handelt es sich um ein Geschenk das sehr viel Freude gebracht hat.

A mi marido y a los niños les han encantado estas cartas. Son una maravilla
