Give the yeast solution a final stir. You are now ready to add the yeast solution, which will start the reaction. You may wish to set up and start your video recording device now. Use the longest focal length lens you have; 2.5″ or 4″ is best, but you can still cut with a 2″ lens if that is all you have. Swirl to mix the reagents, or stir each test tube with a glass stirring rod in turn (Tip: Work from lightest colour, yellow, through to darkest colour, blue, with your stirring rod to enable you to use the same rod).

Using a plastic pipettor, add 3ml washing up liquid to each large test tube (already containing the 25ml hydrogen peroxide).In the five small test tubes, make up the desired colours using three plastic pipettors to measure out the required quantities of each of the primary colours. For example, in the video we used (left to right): Create colourful and fun gifts, toys and craft activities for kids with Crafter’s Companion Funky Foam! Each soft and flexible sheet is super versatile, snip or die cut to any shape you like to craft customised educational games.

Now that you know how to laser cut foam, this next post will show you the best way to utilise your new skills and teach you how to Laser Cut Foam Inserts For Tool Boxes using the toolKaiser App Can You Laser Engrave Pink Insulation Foam? Set up the material in your machine. I placed the foam on my pin bed as it allows for air flow across the top and bottom surfaces and reduces the chance of a flare up. WE WILL NOT BE A PARTY TO OR IN ANY WAY BE RESPONSIBLE FOR MONITORING ANY TRANSACTION BETWEEN YOU AND THIRD-PARTY PROVIDERS OF PRODUCTS OR SERVICES.

Family crafting - The whole family can have fun with Funky Foam! Just snip out your shapes and have fun designing and building fun, personalised projects. We recommend using glue tape pens or a hot glue gun to attach your foam pieces. Please note, adult supervision is required when using scissors and hot glue.How could this reaction be made faster and more spectacular? Tip: Look up spectacular elephant’s toothpaste demonstrations on YouTube. Seal: Closed cutting graphics does not require the use of sealing compensation, but un-closed graphics can be closed by means of it. If, however, the sealing is misplaced, there will be no compensation. Enter a distance, in the seal box, that if the un-closed distance is less than, then sealing is desired. Seal defines the overlap of beginning & end of the cut. A plug cut – this is where the inner measurement is the important parameter and the inner material is the desired component. Having the nozzle closer to the work piece, makes the air assist more effective, however in most set-ups this means the laser beam will be focussed below the surface, giving a larger kerf or cutting width at the top surface.

There was no room for the instructions. However, this is an easy bit of kit to use and the key information is printed on the container. A hole cut – this is where the external measurement is the important parameter and the inner material is disposed of. Imaginative fun - Our premium Funky Foam sheets are perfect for so many fun 3D projects! Create fun party favours, decorations, crowns, pencil toppers, door hangers and so much more. From bugs and butterflies to sea creatures, wild animals and magical fairies - you can make anything you like! Sew Compensation (Kerf Settings): A kerf is the width of the cut made by the laser. By default RDWorks cuts along the centre of the path. This will result in outside cuts being smaller, and inside cuts being larger. The kerf settings allow you to correct for this. My Laser Power Meter Project You do not need a lot of laser power to laser engrave. My typical go to laser engraving settings on my 50W laser is 20% power (about 18 Watts), 400mm/s and a scan interval of 0.2mm. It will of course vary on your machine set-up, but it’s a good place to start.a little bit of orange funky foam for the beak (if you’re using cardboard you will already have plenty!) Work in a shallow Gratnells (F1) tray to contain any drips and the products of the Funky Foam reaction.

Layer 1 had a 32 x 8mm cut out, but I reduced the power by half so that it did not cut all the way through. The interior material was easily removed.

In the 100ml beaker, make up a yeast solution by adding 7g dried yeast into 60ml warm tap water. Give it a good stir and leave aside until needed. Tip: Only make the yeast solution when you are ready to complete the rest of the experiment as it needs to be fresh. Pour sufficient (20ml) washing up liquid into a Gratnells mini-tray or 50ml beaker and leave aside until needed.
