ON PARADE!
Once a year 100 (ish) clowns get together in Bognor Regis and clown around for four days. On Sunday, we have a parade and Bubblz made a mathematical tetrahedral balloon hat to go with her brand new maths costume (by Heidi). Made from four half scale tetrahedra, the hat has an octahedron at the centre of it (look carefully at the red shape).
Bubblz facilitates a similar tetrahedron during her maths workshops. It's a little bit larger - scaled up by a factor of 3, the workshop tetrahedron is nearly 2 metres tall!
