Don’t buy bad quality
So cheaply made when and if it works it only lasts for few seconds and the threads gets tangled quickly it got tangled to the point its impossible to straighten it out again. Waste of money and time. Frustrating!!

The item delivered was much smaller than indicated, the base was only 9cm x 8,5cm and the height was only 9cm. The principle of conservation of momentum was demonstrable and so will be adequate for its purpose. However I was disappointed with the size. This needs to be amended in the product description.
