Miley Cyrus is well known for her wild child antics but she has taken things to a new level with her latest project – a five foot tall homemade bong.

The 21-year-old made the smoking device from fans’ gifts, mainly brightly coloured bracelets, ribbons and toys. The creation also features fake leaves, flowers and two strobe lights. She’s not one to do things by half, our Miley.

Yesterday she took to Instagram to post this video of the crafty piece, with the caption “5 foot bong almost complete, this one is a collab with my f**king beyond kiewl fanz.” Some creative spelling there!

The singer also personalised her delightful new gadget with beads reading “Weed,” “Bangerz” and “Floyd” – the name of her dog who passed away earlier this year.

Miley has been very open in the past about her drug habits. In an interview with Rolling Stone last year, the pop star said “I think weed is the best drug on earth. Hollywood is a coke town, but weed is so much better.”

What would poor Hannah Montana think about all of this?!
