How to Make a Spy Kit for Kids

how to make spy gadgets

Every spy needs a trusty spy kit. Here’s a low-cost idea that you can put together in just a couple of minutes. We’re going to make a set of binoculars and a fingerprint lifting set.

Here’s what you’ll need to get started:

  • Two cardboard toilet paper inners (the brown tube)
  • Black paint and a couple of brushes
  • Rectangular block to join the tubes together
  • Easy to use and safe glue
  • Baby powder
  • Small container with a lid
  • Masking tape or clear tape
  • Powder makeup brush
  • Sunglasses
  • Notepad and pencil/crayon/pen

Spy Gadget 1 – Making the Binoculars

Take the two empty toilet paper rolls. Paint them black and let them dry. Let your kids get in on the painting if you’d like. Put down some newspapers to protect the floor from getting painted too.

Once the rolls are dry, you can glue them to opposite sides of the rectangular block. If they are too wide apart for your kids, you can either tape the rolls together with clear tape or glue them together.

Spy Gadget 2 – Making the Finger Print Lifting Kit

Put some baby powder into the small container with the lid.

The kids will use the makeup brush to spread the baby powder over the fingerprint. Make sure to show them that the layer of powder needs to be very thin.

They’ll use the clear tape to press on the print and lift it off with the fingerprint shown on the sticky side.

You could make a make-do holder for the brush and tape if you’d like, but it’s not necessary.

Putting the Kit Together

Give your kids the sunglasses and a black jacket if you have. Set the scene by laying down semi-oily fingerprints on easy to work surfaces like glass.

Get your kids to scout the area out with the binoculars and have a good time together. Have them arrest you too!

DIY Spy Gadgets Wiki-How Top Ideas

Micro-Camera on a Cap

You will need a bit of a budget. You’ll need to buy a micro-camera. These are tiny cameras that can record to a small card or wirelessly. They’re generally less than $50.

Glue the back end of the camera to a cap, or the middle section of a pair of sunglasses.

Test it out first to see how much time they can record for.

Get your kids to spy on each other and see who gets the funniest footage!

Tell them to set the camera up in the smartest secret spot. They can put it in a bookshelf or pot plant. The creative potential is limitless.

The Corner Spying Mirror

Get a small mirror and fix it to the end of a sturdy shaft. It should be longer than 30cm (12”).

Have the mirror facing toward the holding point of the stick at a 45° angle.

Get your kids to use it to spy around corners and play a game of who can spot the other first without showing their body.

Make sure the mirror has a soft edge so that it doesn’t cut your kids if they touch it.

Secret Code Language and Key

Here are the steps to follow:

  • Cut two evenly rectangular pieces of paper (different colors)
  • Put them side by side
  • On the right-hand side of the left piece of paper, write the alphabet along the edge in a downward column
  • On the left-hand side of the right-hand piece of paper, write the alphabet again, making sure that they line up with each other.
  • Wrap these two sheets around an empty toilet paper tube
  • Fix the ends with tape

The letters should be side-by-side. Mix up the order so that the A is no longer next to the other A. Write down the new matching letter for each row on a separate sheet of paper.

Get your kids to make a message with the code and have them try it on their own.

How to Make a Spy Pen

This isn’t a spy pen with a camera, but rather one that uses invisible ink.

You’ll need to replace the ink of the pen with invisible ink. There are several places you can get invisible ink and a UV light.

Insert the new ink into the pen and have the UV light handy.

Make sure to tell your kids not to shine the light in their eyes.

Write instructions on sticky notes or limbs and have the kids use the UV light to follow the instructions like a treasure hunt.

Each note will take them to a new location or have them perform a task.

This will take a little preparation but it’s very rewarding for your kids. It builds mental acuity and gets them moving around the house.

My favorite is the treasure hunt with invisible ink. I get them to use the binoculars and corner mirror to find the notes around the house.

Take some time to plan something out and your kids will be all the happier for it!

How to Determine the Profit in a Convenience Store

Convenience stores typically offer a large selection of products.

A convenience store’s easy access can command high product prices and strong customer traffic. This can translate into healthy profits for your small business, provided you’re serving the needs of your customers, controlling your costs and pricing your goods appropriately.

Three levels of profit – gross profit, operating profit and net profit – or profit after taxes – can help monitor your convenience store’s performance against the nation’s more than 154,000 stores that generate $233 billion a year, according to a National Association of Convenience Stores report.

Calculate Gross Sales

Add the sales revenue your convenience store generated from your primary revenue sources for the accounting period in question to calculate your gross sales. For example, assume your convenience store sold $50,000 in food and beverages, $75,000 in gasoline and $5,000 in miscellaneous merchandise during the month. Add these to get $130,000 in gross sales.

Calculate Gross Profit

Subtract the amount of any refunds you gave to customers as well as your cost of goods sold from your gross sales to calculate your gross profit. Cost of goods sold represents the amount you paid for the merchandise you sold during the period. In this example, assume you refunded $1,500 to customers and had $90,000 in cost of goods sold. Subtract $91,500 from $130,000 to get $38,500 in gross profit for the month.

Calculate Operating Expenses

Total your operating expenses for the period to determine your total operating expenses. These are the expenses necessary to run your core business, such as rent, utilities, wages, repairs, maintenance and insurance. In this example, assume you paid $3,000 in rent, $1,500 in utilities, $20,000 in salaries and wages, $1,500 in maintenance and $500 in insurance during the month. Add these amounts to get $26,500 in total operating expenses.

Calculate Operating Profit

Subtract your total operating expenses from your gross profit to figure your operating profit. In this example, subtract $26,500 from $38,500 for $12,000 in operating profit.

Calculate Net Profit

Add the income you earned from sources other than from selling your primary merchandise to your operating profit. Subtract the interest paid to creditors, income tax payments and any other non-operating expenses from your result to calculate your net profit after taxes.

A negative number represents a net loss for the period.

Assume you earned $500 in fees from a third-party in-store ATM machine and paid $1,000 in interest and $2,000 in income taxes. Add $500 to your operating profit of $12,000 to get $12,500. Subtract $3,000 from $12,500 for a $9,500 net profit after taxes.

Increasing the Bottom Line

If your convenience store’s profits need a pick-me-up, consider these ideas:

Increase your offerings: Food service sales are increasingly becoming convenience stores’ most profitable category, accounting for 35 percent of gross profits according to the National Association of Convenience Stores.

Offer a lottery option or increase your current offerings. Ninety-five percent of lottery customers buy at least one other item while in the store.

Cut Costs: Replace old institutional-style lighting with new energy-saving lighting. This will save on costs and the softer effect will provide a more pleasant ambiance.

Maintain curb appeal: Eighty-four percent of customers who fuel up say cleanliness is a factor when considering whether to go inside to make an additional purchase.

Give a Cash Incentive: If you sell gas, give a several-cent discount on each gallon of gas when customers pay with cash. Not only will you avoid debit/credit card fees but you will also bring customers into the store to possibly make an additional purchase.

Mirror Advertising: Take advantage of big-box marketing. If a restaurant chain is offering a limited-time deal on a sub, consider offering something similar. Your customers may have seen that ad, have it on their minds and may be primed to purchase it from you if it’s advertised.
