Special FX

Combine dry ice with heated water to produce bubbling water and voluminous flowing fog. Add 2 kg of Dry Ice into a 20 litre container of hot water to create fog for 5 to 10 minutes. As the dry ice cools the water, the volume of Dry Ice fog diminishes. Dry Ice makes fog because of its cold temperature, -78.5°C, immersed in hot water, creates a cloud of true water vapour fog. When the water temperature reaches 10°C or less, the Dry Ice stops producing fog, but will continue to sublimate and bubble. Keep the water heated (using a dedicated dry ice smoke machine supplied by SignFX) to prolong the smoke effect.

Food Presentation

Dry ice is sometimes used in the presentation of food in restaurants. Dry Ice pellets work best as you can add small amounts to serving trays to produce a fog effect around the food dishes. Add the dry ice pellets to warm water to produce the desired fog vapour.

Cold Caps

Scalp hypothermia involves cooling the scalp with ice packs or cooling caps (cold caps) for a period of time before, during, and after each chemotherapy (chemo) treatment to try to prevent or reduce hair loss. Supercooled caps (-20 F to -30F) are worn before, during and after the chemotherapy treatment. This causes the blood vessels beneath the scalp to narrow, reducing the amount of toxic chemical that reach the hair follicles.

The aim of Science Week is to promote the relevance of science, technology, engineering and maths in our everyday lives and to demonstrate their importance to the future development of Irish society and to the economy.

Whether you are organising an event in a school, library or college, there are plenty of resources to help you to get the most out of your event. Use Dry Ice for real life smoke effects, without the smells or dangers of smoke in your classroom. To download posters, science week logos and more. Check out the Science Week website for more details.

Maintaining Goods at Frozen Temperatures

When travelling or camping for a weekend, use dry ice for temperature control to keep goods frozen. Depending on the size of the cooler or ice chest you will need to add between 5kg and 10kg of dry ice. Dry Ice slices are individually wrapped, and can be easily distributed in a cooler or ice chest.

If you wish to keep food chilled rather than frozen then our gel packs may be more suitable.

For a power cut longer than 12 hours, place dry ice in your refrigerator or freezer. To maintain your freezer contents for 12 to 24 hours you will need about 5kg of dry ice. Without dry ice the food will stay frozen for 3 to 6 hours in a fridge freezer, and up to twelve hours for a chest freezer.
