I have a maker/craft project making a kaleidoscope out of three mirrors and a badminton shuttlecock tube (sawn in half).
This will be a project for a class of school kids aged 8-12, so we'll have to teach them to make the item by hand.
Is hot glue (handled by teachers only) the best way to secure the glass triangle inside the tube, or is there a better, long-lasting secure way to fix it in place without risk of dropping out from the tube after several months? Kids safety in mind here.
3x mirrors measuring 2in x 6in each
Sawn shuttlecock tube length is just under 8 inches
