The Whizz Pop Bang Loo Roll Engineering Challenge

Transform your loo roll tubes into engineering masterpieces to be in with a chance of winning 12 Whizz Pop Bang magazines and a binder!

We love an engineering challenge here at Whizz Pop Bang HQ, so we’re challenging you all to get creative with toilet rolls! Show the world your engineering prowess by posting a photo of your structure with the hashtag #whizzpopbangloorollengineering – you could construct bridges, model buildings, miniature playgrounds, anything goes!

To take part, simply build a structure using as many toilet roll tubes (and tubes made from paper and card) as you like, photograph it and post it on social media with the tag #whizzpopbangloorollengineering. Alternatively, email it to with the subject ‘loo roll engineering’.

The five most creative constructions, (as judged by the Whizz Pop Bang science magazine team and their kids!) will each receive a binder full of 12 copies of Whizz Pop Bang, the award-winning science magazine for kids.

Be inspired by Sam’s amazing bascule bridge!

The competition is open to all ages and whole families are encouraged to build together. Teachers, spread the word to your pupils and set them the Whizz Pop Bang loo roll engineering challenge! 

The competition is open until 31st May, which should give you some time to build up your loo roll collections!

The judges’ decision is final. Full terms and conditions of all Whizz Pop Bang competitions can be found here.
