How to use ice or glycerin tubes to cool down the smoke from your glass bong without diluting it?

If you enjoy smoking herb or tobacco from a glass bong, you might have wondered how to make your hits smoother and cooler without compromising the flavor or potency of your smoke. One common method is to add ice cubes to the bong’s water chamber, which can lower the temperature of the smoke as it passes through the water. However, this also has some drawbacks, such as:

  • Adding extra weight and bulk to your bong
  • Making the neck of your bong longer and harder to clear
  • Causing the water level to rise as the ice melts, which can lead to splashback or spillage
  • Diluting the smoke and reducing its strength and taste

Fortunately, there is another way to cool down your smoke without using ice or water: glycerin tubes. Glycerin tubes are glass attachments that have a spiral coil inside filled with glycerin, a non-toxic liquid that can freeze quickly and stay cold for a long time. Glycerin tubes can be attached to your bong or pipe and act as a cooling system for your smoke, without adding any moisture or impurities.

What are the benefits of using glycerin tubes?

Glycerin tubes offer several advantages over ice or water for cooling down your smoke, such as:

  • They are easy to use: you just need to put them in the freezer for a few hours before smoking, and then attach them to your bong or pipe.
  • They are effective: they can lower the temperature of your smoke by over 300 degrees, making it much smoother and cleaner.
  • They are durable: they can last for multiple sessions without losing their chill, unlike ice that melts quickly.
  • They are versatile: they can be used with any bong or pipe that has a compatible joint size.
  • They are stylish: they come in different shapes, sizes and colors, adding some flair to your smoking experience.

How to use glycerin tubes?

Using glycerin tubes is simple and straightforward. Here are the steps you need to follow:

  1. Put your glycerin tube in the freezer for 2-4 hours, depending on its size. You will know it is ready when the bubble inside moves very slowly.
  2. Take out your glycerin tube and attach it to your bong or pipe. Make sure the connection is secure and stable.
  3. Pack your bowl with your favorite herb or tobacco and light it up.
  4. Inhale the smoke through the glycerin tube and enjoy the icy smooth hits.

How to clean glycerin tubes?

Like any other smoking accessory, glycerin tubes need to be cleaned regularly to prevent clogging and maintain their performance. The best way to clean them is to use isopropyl alcohol and salt, following these steps:

  1. Place your glycerin tube in a Ziploc bag and fill it with enough alcohol to cover it completely.
  2. Add some salt to the bag, making sure the grains are small enough to pass through the coil but coarse enough to scrub off the resin.
  3. Seal the bag and shake it vigorously for 2-5 minutes, allowing the solution to flow through the coil.
  4. Leave the glycerin tube to soak in the alcohol for 15-30 minutes, or longer if it is very dirty.
  5. Shake the bag again to remove any remaining dirt.
  6. Take out your glycerin tube and rinse it well with warm running water.
  7. Dry your glycerin tube with a paper towel or let it air dry.
