Dip a sponge or paintbrush into the concentrate and wash the new “decoder ink” evenly over the page that contains your message.  Be careful painting with grape juice; it stains. Don’t use the same cotton swab or paintbrush you used to write the message. As you paint over the surface of the paper, your letters will reappear before your eyes. The letters appear gray because an acid-base reaction occurs between the basic baking soda and acidic grape juice.

Problem: Article: A bike must be the correct size for the rider, or they will have difficulties learning how to ride. Tell the rider to sit on the bike and put their feet on the ground. You can lower the seat, if necessary. If the seat is as low as it can go and their feet still don’t touch the ground, they need a smaller bike. The rider should also be able to comfortably reach the handlebars and brake levers. Though this may seem counterintuitive, removing the pedals will help the rider find their balance by gliding. Use a wrench to remove the pedals on either side of the bike. Put the pedals and hardware in a safe spot where they won’t get lost. To help the rider feel comfortable on the bike, they’ll need to practice getting on and off of it. Tell the rider to apply the brakes when getting on and off the bike to minimize rolling or wobbling. To get on the bike, the rider should lean the bike toward them and swing their leg over the saddle. To get off the bike, the rider should lean the bike to one side and swing their opposite leg over the saddle. Tell the rider to practice this 10 times, or until they feel comfortable. A rider who is comfortable using the brakes will have more confidence when learning to ride. Have the rider push their bike as they walk alongside it and practice using the brakes. Tell the rider to apply even pressure to both brake levers. Once they feel comfortable using the brakes, they can move on to gliding. The rider should sit on the bike with their feet on the ground. Instruct the rider to push the bike using their feet and practice gliding. As they scoot along, they’ll learn what it feels like and what it takes to balance on 2 wheels. They can roll down a slight slope to help them gain momentum and balance. Have the rider keep practicing until they can push off and glide along without putting their feet down to correct their balance. Now that the rider has familiarized themselves with the bike and gotten used to gliding, they are ready to pedal. Use a wrench to replace the bike pedals. Ensure they are secure and that the rider can comfortably reach them while sitting on the bike. Adjust the height of the saddle using an Allen wrench, if necessary.
Summary: Adjust the bike seat so the rider can put their feet on the ground. Remove the pedals from the bike so the rider can learn to balance. Instruct the rider to practice getting on and off the bike. Have the rider push the bike while walking beside it and practice braking. Tell the rider to practice gliding on the bike. Replace the pedals and adjust the seat, if necessary.

This will create a permanent transfer of color between the items, effectively ruining your clothing. Once you realize that dye from one piece of clothing has transferred on to your white clothing, separate the colored piece of clothing from the white clothing. This will prevent additional dye from transferring on to your white clothes.
