This amazing putty will really get you thinking. It looks like it should be a sticky goo, but poke it and it's quite firm.
Form it into a ball and you can bounce it, pile it up in a mound and watch it slowly melt down flat or pull it apart and see it snap.
Bionic putty has such unusual properties that you'll be playing with it for hours.
Glow in the dark Bionic Putty: Put it in the dark and it emits an eerie glow. Spookily phosphorescent!
Bionic Putty comes in 100g pots.
The bottom of the pot says seek medical advice if ingested. To save everyone a whole lot of time we suggest you don't eat it in the first place.
Suitable for ages 8+ with adult supervision.
