Wally's Widgets


Welcome to the launch of our new brand - “Wally's Widgets” and the first product, the Drying Bomb, which is a desiccant to keep small airtight containers dry (often down to 20% Relative Humidity).

The desiccant is called silica gel, which is harmless and looks like tiny beads, almost perfectly round and hard, like sand. The beads are orangey-brown when fully dry turning deep green when they have reached their capacity to remove any more water from the surrounding air. The silica gel beads can hold up to 40% of their own weight in water. The Wally's Widgets Drying Bomb contains 20g of silica gel inside a stainless steel mesh container. That's a huge moisture removing capability of 8ml of water or around two and a quarter teaspoons of water! That's a really powerful dose ideal for difficult applications where moisture is a real problem

Best of all, you can recharge them.

Silica gel is non toxic but the kind of silica gel we use has an indicator. We could have used colourless or white silica gel which is added to some production foodstuffs but we'd lose the ability to see when the beads need recharging. So for that reason we say 'Do not ingest'.

Recharging couldn't be easier. Once saturated with water, the gel can be regenerated by heating it to 120 C (240 F) for 1–2 hours in an ordinary gas or electric oven NOT a microwave.

To charge the bomb, put it on an ovenproof saucer and set the oven (either fan, electric or gas) to 120C, 240F or for gas mark, set it to between Mk and and leave it there for long enough for the beads to dry out fully and turn to a lively orange colour. The stainless bomb is perfectly alright at much higher temperatures than this. These directions are on the inside lid of the Drying Bomb.

Bomb with open lid

Silica gel is so effective, if you leave some out in an open place they will quickly saturated and turn dark green. You need to put the bomb into an airtight container or use a plastic bag if you prefer. We usually use lunchboxes and other 'Tupperware' type containers.

There are hundreds of uses in every home. A dry atmosphere prevents mould, rust, corrosion and moisture damage. It also prevents powders from caking and paper from degrading.

Fishing – protect your reels, spinners, hooks, knives

Camping – keep your matches really dry, soggy matches don't work well!

Hearing Aids – It really does pay to keep your hearing aid(s) in a dry box when you are not wearing them. The drying effect helps to prevent the growth of moulds, bacteria and damage to the delicate electronics

Jewellery – Precious metals and stones are not usually damaged by moisture but mould can grow in crevices. In the case of gemstones they can lose their sparkle. However NEVER store genuine pearls in a dry place or they WILL dry out and crack. The ideal place to store genuine pearls is round your neck! The Drying Bomb is ideal for your costume jewellery which often starts to corrode after very little use.

Powders, chemicals, etc. – powder paints, watercolour sketch books; you can drop a Drying Bomb into a document or artist's cardboard tube but make sure the ends are on. A plastic tube would be much better or you can wrap some plastic tape (insulating tape) along the tube to help stop the moisture getting through the wall of the tube.

Medicines – if you keep pills for any length of time in humid areas, then put the medication packs into a Tupperware container and put in a Drying Bomb. This will keep your medication tinder dry even in very humid parts of the world and of course it is easy to recharge them almost anywhere, even in an hotel if you ask the kitchen staff. Keeping medication dry will often extend its shelf life even in the temperate climate we enjoy in Britain.

Tools – steel tools rust, keep them dry with a Drying Bomb

Stamp collections and your stock of stamps

Valuable books, photos, scrapbooks, diaries, notepads, etc

Rescue of water-damaged personal electronics such as iPods, mobiles, tablets, MP3 players, keep-fit monitors. The usual advice is to shake out all the free water wipe with a towel and leave them to dry for several days. If you put them into a small lunchbox with a freshly-charged Drying Bomb the Relative Humidity will fall to around 20% which dries out the electronics much, much faster and reducing the damage moisture causes drying slowly.

The packaging industry usually estimate one gram of silica gel per litre (1 pint) volume. So the Drying Bomb with its whopping 20 grams is suitable for up to 20 litres (35 British pints). In most cases the container you use will be much smaller than that, so it will last longer. I've had an electronic outdoor temperature sensor outside my office window, in a screw-lid Tupperware beaker of around 250ml for coming up to eight months protected by one Drying Bomb and the silica gel is STILL orange. When the capacity is becoming used up you can see a few beads starting to change colour. That's the time to recharge the Bomb.

This is a fabulous well-made product designed and made by us on the glorious Isle of Wight providing work for Britons and keeping more of our pounds sterling in the UK rather than giving it to our overseas competitors.
