I made this lava lamp using a 750 ML Absolut Vodka Beri Acai bottle from Sweden. The lava is purple to match the bottle, a beri complementary combination! Do you know someone who likes Beri Acai vodka? They'll love this lamp! Check out my feedback. I've been making and selling these lava lamps on Etsy for years. Let me know if you have any special requests.
