MATHS GEAR IS TEMPORARILY CLOSEDUK residents have been asked by the government to stay in their homes because of COVID-19. We won't be able to fulfill orders until the curfew is lifted. Sorry for the inconvenience.
Are your balloons topologically trivial? Do you party harder than a mere spherical balloon can handle? Then you need... a torus!
These Toroidal balloons have a much more interesting structure than a standard-issue sphere, and can be used to:
- Liven up parties
- Decorate your home or office
- sketch non-planar graphs and maps that require up to 7 colours
This pack contains 5 balloons in assorted colours. Fully inflated, they measure 16" across and have an Euler Characteristic of zero.
Balloon colours will be chosen at random (although we can't guarantee a truly stochastic selection process).
